![]() The physical-mechanical properties of the prepared mixtures were investigated for water-saturation and strength parameters and the corresponding dependences were obtained. Mix for cold recycling technology were designed on bitumen emulsions with hydrochloric and orthophosphoric acids and with stone materials (virgin aggregate) of acidic granite and alkaline carbonate rocks, reclaimed asphalt, Portland cement and water. The difference was determined between the indicators of storage-stability for cationic bitumen emulsions using hydrochloric and orthophosphoric acid. The study was performed for the special interaction of road cationic bitumen emulsions with orthophosphoric acid and Portland cement, which manifests itself during the determination of parameters of bitumen emulsion disintegration. Road cationic bitumen emulsions with hydrochloric and orthophosphoric acids were selected and compared with the help of establishing their physical and mechanical parameters. Long storage stability in clean containers/Tanks.įlexibility on viscosities for different applications.Investigated is the use of orthophosphoric acid (which is unconventional for road cationic bitumen emulsions) with a special emulsifier for the cold recycling technology of road pavement. Since heating to high temperatures is not required it has less impact on environment. It can be used in any season, and between temperatures of 8 and 50 degrees Celsius. Provides better tack coat with better workable conditions. Road repair work can be carried out in minimum time. It can be used in damp environment on wet aggregates. Slow Setting (SS-2): It is used for slurry seal, road mixes and for prime coat applications.Slow Setting (SS-1): It is used for Prime Coat.Medium Setting (MS): It is used for repair work/ surface dressing/ penetration macadam. ![]() Rapid Setting (RS-2): It is recommended for surface dressing, grouting.Rapid Setting (RS-1): It is Recommended for tack coat applications.Emulsified bitumen acts as a key tool in road maintenance and construction technology as it combines amazing versatility while offering multiple comparative advantages.Īs Per IS 8887:2004, We manufacture 5 grades of Cationic Bitumen Emulsion. It can, however be transformed into a workable state by blending with petroleum solvents or by emulsification with a surfactant in water to form a bitumen emulsion. The strong adhesion that occurs between the bitumen emulsion and mineral aggregate/stone enables the bitumen emulsion to act as a binder, with the mineral aggregate/stone providing mechanical strength for the road.īitumen alone is difficult to work with, at ambient temperatures since it is a highly viscous material under these conditions. In road making, bituminous products are typically applied with mineral aggregate/stone. They are prepared as emulsions at high temperatures, but applied as solid dispersions at ambient temperatures. Bitumen emulsions are a dispersion of bitumen in an aqueous continuous phase, stabilised by the addition of an emulsifier. Today the main use of bitumen emulsion is in the road making industry for construction and maintenance.
