The most important reason contributing to this condition is improper adhesion between bitumen and commonly used aggregates, salt contamination of water/soil and water drainage problems. Majority of aggregate show high stripping value (as high as 70%) and most of them fail miserably in bitumen adhesion properties. These conditions prevail across continents, thus all around the world, anti-stripping agents are recommended and used to extend pavement life. Moisture DamageSince this is well established that Bituminous Pavements suffer from water damage, this damage can result in rutting, shoving, ravelling, bleeding, cracking and formation of potholes. More importantly this can also lead to loss of chippings from surface dressings (chip-sealing) and freeze-thaw damage in snow-bound area. The reason for this problem on a micro scale is loss of adhesion between the bitumen and the aggregates. There are very few types of aggregate which can resist the action of water, because the water can enter the pavement structure in a number of ways: Wet bitumen-aggregate interface on aggregate not dried properly. Rain water seepage through shoulders, cracks or pores, ground / sub-surface water exhibiting a hydrostatic action (moving inside bituminous layer). Capillary water sucked and expelled out from the top or subgrade. Water vapors formed in the subgrade due to hot weather. The factors contributing to moisture damage of these pavements includes: Siliceous type and dusty aggregates. Presence of clay on aggregate surface. Bitumen with higher acidity profile. Mix designs with less binder and open grading of aggregates. Material with higher voids due to improper compaction. Inadequate drainage. Presence of water vapors between layers. Adhesion of BitumenBitumen is the semisolid material obtained from distillation of crude petroleum oil. It is largely made up of hydrocarbons with low polarity hence it has a very low reactive index and shows little chemical affinity for aggregate, whereas most of the aggregates are ionic so they have high affinity for water. This shows that bitumen can be easily displaced by water, leading to separation of bitumen layer from aggregate.Being the distillate of crude oil, bitumen contains a number of organic substances. Presence of naphthanic acid and other carboxylic acids make the Bitumen slightly acidic, so with siliceous aggregates repulsive forces makes the bonding inefficient. This may lead to the problem of stripping and failure of bituminous pavements. There is only one cause of stripping: water getting between a bitumen film and the aggregate surface, replacing the bitumen as the coating of the aggregate. Practically the adhesion between bitumen and aggregate depends on the source of the bitumen and the chemistry of the aggregate surface. The Aggregates can be of an "acidic" type with surface showing negative charge, or "basic" with surfaces showing positive charge. Acidic aggregates include high silica content rocks, while basic aggregates include carbonate mixes. Bitumens, especially those with high acid value, show a tendency to become negatively charged resulting in adhesion problems (particularly with acidic aggregates). Although water damage is highest in wet climates and high traffic roads show such damage most quickly, but this problem can occur in all climates. Adhesion PromoterThe chemical affinity between bitumen and aggregate can be improved by the addition of very small quantities of chemicals which change the nature of the aggregate or the bitumen to have more affinity for the other. These chemicals are known as "Anti-stripping Agents" "Anti-stripping Additive" or "adhesion promoters". Since the stability of bituminous pavement largely depends on adhesion between bitumen and aggregates, the ionic nature of aggregate is an important factor explaining the problem of stripping that differ for different type of aggregates.This also explains non-formation of stable bond in bituminous pavement construction. (refer IS-6241:1971 "Method of test for determination of stripping value of road aggregates, ASTM D3625 "The Boiling Water Test"). The widely accepted class of Anti-stripping agents belong to Fatty Polyamine group of chemicals where even in a very small dose they provide: Active and passive adhesion between Bitumen and the aggregates, Being surface active agents they provide bituminous wetting action (in some cases, reduced requirement of Bitumen), and prolongs the pavement life by slowing the ageing process. Pavement StabilityAlthough the use of Anti-stripping Agents can not eliminate the pavement damage problems caused by poor pavement design, bad construction techniques or poor materials, but mostly helps to minimize their effect.The twin aspects of pavement stability are: Bituminous wetting: whether Bitumen properly coats the aggregate surface or not? Resistance to stripping: whether Bitumen sticks to the aggregate for lifetime of the road or not? Poor wetting can be avoided by the modification of the bitumen properties or by the modification of the aggregate surface. The aggregates can be pre-coated with kerosene or water solution of Anti-stripping Agent to make the surface more receptive to the bitumen. But more practical approach is to modify the binder properties by the adding Anti-stripping Agent additives also known as "adhesion promoters", "wetting agents" or "Anti-stripping Compounds"DERBO & WETBOND RangeThe problem of stripping can be effectively minimized using "DERBO" and "WETBOND" range of anti-stripping agents. Since they are made from Polymeric amines, the amine group of "DERBO" and "WETBOND" anti-stripping agents reacts with acidic aggregates and makes the aggregate surface hydrophobic (repulsive to water). Further lipophilic (oil loving) Fatty chain remains well suspended in bitumen to form a bridge between bitumen and aggregates. This prevents stripping even in presence of water.Amine based "DERBO" and "WETBOND" Anti-stripping agents also act by changing the interfacial tension between Bitumen and aggregates and strengthening the bonding for long term durability. In construction of bituminous pavements, the aggregates are used in two ways e.g. in coated form (Hot Mix etc.) and uncoated form (spraying work etc.). When used in proper dose, "DERBO" and "WETBOND" are equally effective in both the applications. In coated form they prevents stripping even when coated aggregates are submerged in water and in uncoated form they provides active adhesion of bitumen even with wet aggregates. DoseDosing of DERBO and WETBOND can be done at different stages of mixing and application. An automatic dosing system can be installed in hot mix plant, however an easier way is to add pre-determined quantity in bitumen storage tank before unloading the bitumen from bulk tanker. Alternatively it can be mixed in stored bitumen by gentle stirring for 15 minutes by a mechanical or manual process. The required dose of each grade will be different depending on type of bitumen used, type of aggregates and type of surfacing. (The dose can be estimated by some simple tests covered under testing page)TestingsProducts are tested from: Central Road Research Institute, New Delhi. Indian Institute of Petroleum, Dehradun CEG Test Lab & Research Center, Jaipur Delhi Test House, Delhi Shriram Institute of Industrial Research, Delhi U.P.P.W.D. Research Institute, Lucknow. and many more... Common tests for on-site evaluation of the efficacy of Anti-stripping Agents are:Coating Retenion Test :A test similar to stripping test where the blends of different doses of Anti-stripping Agents (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0%) in hot Bitumen are prepared and 10 gms of each blend is mixed with 200 gm hot aggregates and placed in a beaker to cool. Each beaker is then filled with distilled water to submerge the aggregates and placed in water bath maintained at 40°C for 24 hrs. After 24 hrs, each beaker is visually inspected to determine the percentage of Anti-stripping Agent sufficient to retain more than 95% coating.Under Water Coating Test :Different blends of Anti-stripping Agents (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0%) are made in bitumen cutback MC-30. In a 1-litre capacity tin container, 200 gm aggregate are taken and 750 ml of warm distilled water (at 40°C) is poured inside. On top of water, 10 gm of bitumen-antistripping blend is poured. The container is then capped and shaken vigorously for 2 minutes. Then water is drained out and aggregates are transferred on white paper. Percentage of area of aggregates coated with bitumen inside water is then visually estimated.Boiling Test :Blends of different doses of Anti-stripping Agents (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0%) in Bitumen are prepared and each mixed in 10 gm quantity with 200gm aggregates and put in a beaker to cool. Each beaker is then filled with distilled water to submerge the aggregates and boiled vigorously for 10 min. After 10 min water is drained and the aggregates are transferred to white paper where retained coating is visually estimated.Retained Marshall Stability :Test specimens are prepared with 5% Bitumen/ Bitumen-Antistripping Agent blends. One group is placed in water at 60°C for 40 min and tested for Marshall Stability. The other identical group is immersed in water at 60°C for 24 hrs. and then tested for Marshall Stability. The Retained strength is then calculated by determining the percentage of Retained Marshall Stability.ApplicationsHot-Mix Surfacing :Hot Mix surfacing is the most efficient and preferred road construction technology. This however requires stringent control of performance features like stripping which most of the times shortens the pavement features and life. This problem can be minimized by using small doses of DERBO that also results in Bitumen saving and good saving in maintenance.Surface Dressing (Chip-Sealing) :Surface dressing (chip sealing) involves spreading uncoated chippings over a sprayed layer of Bitumen followed by rolling. The applied Bitumen layer cools rapidly leading to wetting problems which become worse by wet and dusty aggregates. In this case an active adhesion is required and typically 0.5-1.0 % DERBO is added to the bitumen. Alternatively the chippings can be pre-coated with a mix of diluted binder and DERBO or a diluted water solution of DERBO can be sprayed on chippings before spreading. Field studies have demonstrated that the use of Anti-stripping Agents in surface dressing provides resistance to early rain.Maintenance :When repair works like pot-hole filling, crack sealing, rutting etc are carried out in rainy season or where possibility of moisture damage is high, a little addition of Anti-stripping Agent ensure stable repairs.Hot Recycling :When a pavement is subjected to hot-recycling, if partly coated surfaces are observed in the reclaimed mix, to provide easy wetting, better water resistance and better compaction, Anti-stripping Agent should be used.Emulsions :Cationic bitumen emulsions provide good adhesion in road applications but sometimes an additional water resistance is required. Anti-stripping Agent can be added to the binder before emulsification. Anionic emulsions generally provide poor adhesion to siliceous (acidic) aggregates. Adhesion of anionic emulsions can also be improved by adding Anti-stripping Agent to the binder before emulsification, or to the finished emulsion.Precoated Chippings :When chippings are lightly coated with bitumen, kerosene or diesel to ensure adhesion in surface dressing or when rolled into hot rolled bituminous surfaces to improve skid resistance, Anti-stripping Agent can be added to the coating material to ensure good adhesion.Prime Coats :Where cutbacks are used for priming and dust control during construction, since road base retains moisture and remains cold, Anti-stripping Agent should be added to the prime coat to ensure active adhesion and protection from moisture. Antistripping Additive http://www.petrochemspecialities.com/antistripping-additive.htm http://www.petrochemspecialities.com/antistripping-additive.htm Wed, 30 Oct 2019 00:00:00 +0530 Introduction : Nano-technology based Anti-stripping Additives are the latest innovation in asphalt road construction technology. Acting as an adhesion promoter and water proofing agent, these additives utilize the bond formation at molecular level, so they are low dose products with ultimate thermal stability. Our Nano-technology products work on synergistic combination of molecular amine and silicon acting as reactant as well as facilitator for active bridge formation between road aggregates and bitumen. The bond formation by these additives are very stable and provide a very long water protection for the treated surface.Mode of ActionNano-technology based Anti-stripping Additives are based on silicon and amine molecular chemistry. These products assist in formation of a non-reversible covalent bond between bitumen and silica present in road aggregates. Since this bonding is at molecular level, it is one of the toughest in present day chemistry, which is resistant to the action of higher temperatures or water.When these innovative Nano-technology products are mixed with bitumen, the polyamine groups react with organic acids present in bitumen and create a basic environment beneficial for stronger bitumen-aggregate bond formation and molecular reactive silicon forms complex silicon bridge intermediates.When the Nano-technology anti-stripping additive treated bitumen is mixed with common road aggregates, the active silicon bridge intermediates in bitumen readily form covalent bond with nearest silicon molecules on aggregate surface. This bond is physically and chemically resistant so it does not allow ingress of water between bitumen-aggregate interfaces.Since the active silicon bridge formation takes place at molecular (Nano) level, a small dose of these products are enough to achieve complete protection from water damage. WETBOND-SWETBOND-S"Wetbond-S" is next generation Nano-technology Silicon based Anti-stripping Additive for Asphalt. This product is a low dose and extremely thermal resistive additive for use in Hot-mix and Warm-mix road constructions. This product is specially suitable for aggregates having very high and tough to control stripping profile.Physical Properties :"Wetbond-S" is brownish clear liquid at room temperature with characteristic citrous odour. This product is non-miscible with water and miscible with polar & hydrocarbon solvents. The thermal stability of this product in hot bitumen (at 160°C) is over 15 days and no additional dose addition/adjustment is required on prolonged storage in hot bitumen in normal course of Hot-mix and Warm-mix pavement constructions. As this product is used in a very low dose, it does not have any effect on physical properties of paving bitumen of any grade including VG-10, VG-30, VG-40, CRMB or PMB (Elastomeric & Plastomeric types) towards Penetration, Softening Point, Ductility etc. However the chemical properties are changed tremendously as the bitumen becomes more receptive to aggregates and bonding between aggregates and treated bitumen becomes highly resistant to stripping even under extreme atmospheric conditions. This ensures long term pavement durability without affecting the quality of work. This product is suitable for production of Refinery-treated non-stripping bitumen, Hot-mix pavement constructions, Warm-mix constructions and for industrial bituminous coatings.Advantages :Wetbond-S" is oily liquid product for premixing or direct injection in Bitumen. This product has several advantages over conventional Anti-stripping Agents: Very low dose product, no effect on bitumen properties. No degradation when stored in hot bitumen, saves money. Nano active amine and silicon based, works on molecular level. High amine value for active bridge formation between Bitumen and aggregates. High Nitrogen content gives excellent performance even with moist aggregates. Readily soluble in hot bitumen, so fit even for direct dosing in HMP. Non Hazardous product for safe handling and storage. Economical as compared to conventional products in dose dependent comparison. Storage and Handling :Wetbond-S" can be stored in HDPE or MS drums / tanks at a cool and dry place at ambient temperature.

This product can also be used for Refinery mixing.Storage and handling :WETBOND-SX can be stored in steel or HDPE tanks. Heating above 50°C should be avoided. Minimum exposure to air is the key for long storage stability. WETBOND-SX contains Organic Silicon derivatives so it can cause mild irritation to skin, eyes and lungs. Protective gloves, mask and goggles must be worn during handling and use of this material. Avoid inhalation. Additive (Dose)Dosing of WETBOND Nano Technology can be done at different stages of mixing and application. An automatic dosing system can be installed in hot mix plant, however an easier way is to add pre-determined quantity in bitumen storage tank before unloading the bitumen from bulk tanker. Alternatively it can be mixed in stored bitumen by gentle stirring for 5 minutes by a mechanical or manual process. The required dose of each grade will be different depending on type of bitumen used, type of aggregates and type of surfacing. (The dose can be estimated by some simple tests covered under testing page of Anti-Stripping Agents) Warm-Mix Additive http://www.petrochemspecialities.com/warm-mix-additive.htm http://www.petrochemspecialities.com/warm-mix-additive.htm Wed, 30 Oct 2019 00:00:00 +0530 IntroductionHot-mix road construction contributes considerably in global warming and increased gaseous emissions. Hence the new focus for road industry is to lower its emissions by reducing the mixing and compaction temperatures of the bituminous mixtures without affecting the properties of the paving mix.Warm mix additives are chemicals used to reduce the mixing and compaction temperatures. A significant reduction of required heat can be achieved in most cases.Even though there are water based warm mix additives available which facilitate low temperature compaction by inducing foaming of hot bitumen, they have inherent problem of escalated water damage to prepared pavements. The other class of amine based warm mix additives provide non-foaming characteristics to prepared bitumen and asphaltic mixtures and in addition provide protection from water damage (Anti-stripping effect). Hence Amine based warm mix additives are preferred over others.Physical properties:Yellowish White flakes and powder at room temperature with characteristic fatty odour, Insoluble in cold water but miscible with petroleum solvents. Improves flow properties of bitumen. No significant effect on bitumen properties. Does not contain water so does not create foaming in bitumen. No additional anti-stripping agent is required in warmmixes made using WETBOND-WMA.Storage and handling :WETBOND-WMA can be stored in Airtight Bags or Carboys. Avoid storage above 50°C as this can cause agglomeration. Minimum exposure to air is the key for long storage stability. WETBOND-WMA contains amines and may cause irritation or burns to the skin and eyes. Protective goggles and gloves must be worn during handling of this product. Solid Thickener http://www.petrochemspecialities.com/solid-thickener.htm http://www.petrochemspecialities.com/solid-thickener.htm Wed, 30 Oct 2019 00:00:00 +0530 Thickeners are used to increase the viscosity of a liquid system to adjust its flow properties.Bitumen Emulsions have a lot of variation in their viscosities depending on the type of bitumen used, type of emulsifier, dose of acid, particle size distribution etc. Most of the time an external viscosity improving agent is required to meet specifications and coating properties.Solid thickeners are the powders obtained from complex natural products modified by chemical cleavage and re-formation to provide stability in low pH meadium. "BeGel" is a modified polygalactomanan type low dose product which is compatible with most grades of Bitumen Emulsion and emulsifiers. This product is added into hot water before formation of Bitumen Emulsion to obtain high viscosity.Physical properties:Fine Power in light yellow colour with chararcteristic Odour, substantially non-hazardous but irritant on prolong contact. Dispersible in water, giving thick colloidal dispersion. Shows mild alkaline pH in water.Typical Doses & method of addition :BeGEL should be used between 0.1% to 0.5% w/w of Water. BeGEL should be added to hot water (Temperature between 50 and 80 Degree centigrade) in smaller quantities using a dispersing device like sieving through 0.6 mm sieve with constant stirring to avoid lumping. Stirring should be continued for 15 minutes and then the liquid can be used normally in place of water. If lumping occurs, the liquid can be filtered through 0.6 mm sieve to avoid agglomeration.Storage and handling :BeGEL can be stored in air-tight containers/polybags in a cool and dry place. If exposed to air, the product can absorb moisture and lumps can form, in such case the material can be dried in hot-air oven at a temperature of 100° centigrade for 1 hour followed by cooling in desiccators and grinded to a fine mesh.Inhalation of dust can cause suffocation. Protective face mask, goggles and gloves must be worn during handling this product. Liquid Thickener http://www.petrochemspecialities.com/liquid-thickener.htm http://www.petrochemspecialities.com/liquid-thickener.htm Wed, 30 Oct 2019 00:00:00 +0530 Thickeners are natural or synthetic substances which are used to increase the viscosity of a liquid system. A thickener can be liquid or a solid depending on the source of raw material and intended applications.To increase the viscosity of bitumen emulsions, mostly the residual bitumen is increased which in turn increases the cost to a very high level. Few emulsifiers claim to increase the viscosity and storage stability of Cationic Bitumen Emulsion but a fine balance of dose is required as low dose does not increase viscosity and a slight higher dose develops lumps in final emulsion causing it to fail in sieve test. Also prolonged storage of Bitumen Emulsion in open under hot and cold conditions cause the Bitumen Emulsions to cream (separation of water and formation of hard bitumen layer) and site dilution of Bitumen Emulsions by road contractors causes the breaking of emulsions which are serious issues for emulsion manufacturers.Cationic Bitumen Emulsions contains cationic emulsifiers which are stabilized using strong acids like HCl under very low pH. Most of the natural and synthetic thickeners are not stable on this pH and disintegrate within hours of addition causing sharp fall in viscosity."PSEM-THX" is liquid thickener specially designed to remain stable in low pH conditions and can be conveniently blended with any Cationic Bitumen Emulsion. Unlike solid thickeners which require blending with soap water before making Bitumen Emulsion, "PSEM-THX" can be easily mixed after making bitumen emulsions and provide excellent viscosity increase with low dose requirement."PSEM-THX" in addition to increased viscosity, also make Bitumen Emulsions better stable on storage. A Cationic Bitumen Emulsion stabilized with "PSEM-THX" remains fully usable for minimum 1 year even when stored in open area during summers and winters. "PSEM-THX" also prevent breaking of Bitumen Emulsion on addition of water (even in high volumes). Physical properties:Turbid white thick liquid at room temperature with characteristic odour,. Miscible with water and Cationic Bitumen Emulsions of all grades. Ready to use product for post-addition after formation and cooling of Bitumen Emulsion. Improves viscosity, storage stability and the water dilution properties of bitumen emulsion. Stable even on very low pH.Storage and handling :PSEM-THX can be stored in MS or HDPE Barrels. The product is water based and very thick. Product can be diluted in correct proportion with water and used conveniently. RAP Rejuvenator http://www.petrochemspecialities.com/rap-rejuvenator.htm http://www.petrochemspecialities.com/rap-rejuvenator.htm Wed, 30 Oct 2019 00:00:00 +0530 Being a petroleum based product, Bitumen is prone to deteriorate over time due to oxidation caused by environmental, chemical and physical factors. The process of oxidation results in loss of oil and resin fractions of Bitumen making it hard and brittle. When oxidized to greater extent, bituminous surfaces start to show the signs of fatigue including loss of fines, development of cracks and water seepage. This condition finally leads to failure of pavement.The classic properties of bitumen can be restored by adding the specialized additives to replace lost fraction of Oils, resins and organic sequesterants. The additives are called Rejuvenating liquids.During the process of milling and relaying of Bituminous pavements, a huge quantity of crushed bituminous mix is generated which is called "Reclaimed Asphalt Pavement (RAP)". Due to its brittle nature, it is generally wasted in the form of landfill or dumping. The addition of a small quantity of "WETBOND-RE1" RAP Rejuvenator revitalizes this mix and after addition of a small quantity of fresh bitumen, the same RAP can be re-used for fresh surfacing. "WETBOND-RE1" replaces the essential oil fraction, restore flexibility and protect bituminous pavements from damage due to water.Physical properties:Dark red/brown coloured free flowing liquid at room temperature with characteristic fatty and acrid odour. Highly miscible with hot bitumen, oxidize and rejuvenates bituminous layers on Reclaimed A sphalt by fortifying malte n fraction of bitumen and by reversing field oxidation due to continuous exposure to atmospheric conditions and UV radiation. This product has inherent Anti-stripping and UV protection properties thus it minimizes water damage and field oxidation even in extreme conditions.Storage and handling :WETBOND-RE can be stored in Mild Steel tanks. Heating should be avoided. Minimum exposure to air is the key for long storage stability. WETBOND-RE contains fatty acids and amine based compounds so may cause irritation of skin and eyes. Protective goggles and gloves must be worn during handling of this product.Packing information :WETBOND-RE is available in MS barrels of 180 Kgs net weight. Cationic Latex http://www.petrochemspecialities.com/cationic-latex.htm http://www.petrochemspecialities.com/cationic-latex.htm Wed, 30 Oct 2019 00:00:00 +0530 Product Description :Modification of Bituminous products requires addition of an ingredient which changes the rheological properties specially elasticity, resistance to wear deformities etc. In India most of the aggregates used for Road Construction bears a negative charge, using a negatively charged modification material like Anionic latex causes the formation of improper bonding under the stress of repulsive forces."CATLAX" is the cationic latex of Natural Rubber introduced by Petrochem Specialities, which gives an excellent bonding and compatibility with Bitumen and different aggregates. Specially made under controlled process, this Latex provides a better alternative to imported Latex of Synthetic Rubber eg. SBR. "CATLAX" saves time and money and utilises vast production of Natural Rubber Latex of our own country. Composition :"CATLAX" is a fine suspension of positively charged particles of Natural Rubber in water under the balancing force of stabilizing agents. The pH is slight acidic within the range of 5.5 to 6.5. The solid rubber obtained from "CATLAX" shows the same physical properties, as that of obtained from natural latex, however there is slight variation in affinity profile.Compatibility :"CATLAX" is primarily compatible with most of the Bitumen Grades and Cationic Bitumen Emulsions. However a preliminary compatibility testing needs to be done before using this product in bulk. The product is readily miscible with common grades of Cationic Bitumen Emulsions and modifies their performance profile ("CATLAX" can be added to Cationic Bitumen Emulsion just before milling in colloid mill or at the time of use), also it can be added to molten bitumen, however precautions must be observed as latex contains good amount of water. After addition, modified Bitumen Emulsion or modified bitumen can be used as usual.Mode Of Addition :As "CATLAX" is readily dispersible with most of the Cationic Bitumen Emulsions, It can be added to Emulsion drums by simple pouring into barrel and after fixing the lid tightly, rolling the drum for 10 minutes. It can be added to bulk storage tanks fitted with mechanical stirrers ensuring proper distribution on the Latex. The most convenient method is to mix it with soap phase and then mill with Bitumen in colloid mill to get ready Modified Bitumen Emulsion. For Modified Bitumen, it can be added directly to molten bitumen and then stirring well.Recommended Dose :The dose for "CATLAX" varies for different formulations however we recommend a dose between 2 to 4% w/w.Storage & Shelf Life :"CATLAX" must be stored in a cool place in non-metal container and can be stored for a period of 1 year from the date of manufacture. Periodic Shaking is required to avoid creaming. Being cationic "CATLAX" is corrosive in nature hence care must be observed to avoid storage in metallic vassal. Care should be taken while handling and mixing the material, Wear protective mask, gloves and goggles during handling and mixing. Avoid spillage in unintended place. Bitumen Emulsion http://www.petrochemspecialities.com/bitumen-emulsion.htm http://www.petrochemspecialities.com/bitumen-emulsion.htm Wed, 30 Oct 2019 00:00:00 +0530 Roads are the backbone of a country's economy but the high level of emission generated in paving of conventional asphaltic pavements is always a major concern. To reduce carbon emissions during the life cycle of roads, major maintenance using conventional hot-mix techniques must be reduced. Anti-stripping Agent is the green chemicals to reduce water induced damage to bituminous pavements and extend the life of the pavement. These products are used at the time of road construction with conventional hot-mix surfacing. Bitumen Emulsions are cold-mix products for road construction and maintenance. Since they do not require heating before use, the worldwide use of Bitumen Emulsion is growing rapidly. Bitumen Emulsifiers are the products which are used to stabilize the fine suspension of Bitumen droplets inside water.

Highly miscible with water, gives soap like solution. The water solution has low pH suitable for production of cationic bitumen emulsions of Rapid / Medium setting grades. Emulsion Production methodology (using standard on-site production plant) :Hot bitumen at 135-150°C is kept ready in bitumen dosing tank of emulsion plant. In water dosing tank, soft water (free from harmful salts) is heated to 70°C, then required dose of PSEM-RMS-DMR is poured in water and stirred for 5 minutes (referred as soap solution). The soap solution and hot bitumen are then fed to the colloid mill in proper ratio and the final emulsion coming out of colloid mill outlet is collected in a storage tank. The final emulsion is then cooled and used as required.Storage and Handling :PSEM-RMS-DMR can be stored in HDPE tanks. Material can gel upon prolong storage in cold temperature, but all the properties remains equally good. PSEM-RMS-DMR contains acids for pH adjustment and may cause irritation or burns to skin and eyes. Protective goggles and gloves must be worn during handling this product.
