Physical Properties :

  • “COOLTAR-CE” CQS grade is fine dispersion of bitumen, latex polymers and performance additives in water stabilized by very special grades of high performance cationic emulsifiers and stabilizers. This PME is free flowing brown viscous liquid in cold state and is ready to use product at project site.
  • Since the stone aggregates (specially Stone dust) and environmental conditions are different project locations, to ensure proper mixing of PME with other components of micro-surfacing in pug mill of special paver and then application of same on the road surface in a definite thickness, consistency and texture, each site requires a different mix design with change in PME formulation.
  • The design process of COOLTAR-CE CQS grade starts with detailed analysis of stone dust and coarse aggregates collected from the project site. Based on gradation, reactivity and physical properties of these aggregates, different formulations of PME are made in lab scale bitumen emulsion plant and tested for mix properties and performance after setting.


Important Parameters of PME : 

  • Polymer Modified Micro-surfacing Emulsions (PME) are the most important component of this technology as they have to bear the entire stress of traffic and environmental conditions to perform for years at application site. Since they are applied in a thickness of only 6 to 8 mm, it becomes even more important for the PME to provide: mechanical bonding, elastic strength, anti-oxidation properties, continuous mat, skid resistance, water repellency,  fine texture and prevent raveling.
  • MoRTH and IRC:SP-81 have standard specifications for Micro-surfacing emulsions in India, which needs to be strictly followed to ensure stability of micro-surfacing layer for years. The most important parameters are Softening Point, Elastic Recovery, Penetration Value and Ductility of binder recovered after evaporation of water from the PME.
  • The MoRTH and IRC also specify the tests to be conducted on micro-surfacing mix to estimate the performance in field which include Wet Cohesion Test, Consistency Test, Wet Track Abrasion Value, Boiling Water Stripping Test etc.
  • We at Petrochem Specialities have complete laboratory setup including lab scale bitumen emulsion plant, complete testing equipment, mix design facility, reliable commercial scale bitumen emulsion batch plant, micro-surfacing machinery and after sales support system for our esteemed customers.
