The Premature failure of Bituminous Pavements due to action of water is the most common problem and single biggest factor causing early pavement distress. 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.
Bitumen 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 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
The 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
Although 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.
