CATIONIC ASPHALT EMULSION FOR PRIME COAT

摘要

A cationic asphalt emulsion for prime coat according to this invention can be used as prime coat for road base course - both untreated base course and treated base courseOnce the asphalts dry, they will securely adhere to the base course. It's convenient to use since no need to heat asphalt emulsion while using. The viscosity can be altered by adding the water, so no fire hazardous during heating. The traffic can be back to normal without spreading sand. Besides, the cost is much lower compared to the cutback asphalts, and also less volatile hydrocarbon solvent emissions into the atmosphere. Other than road construction, it can also be applied in other applications, such as temporary covering road in the mine or road under construction, covering open space to reduce airborne dust generated by wind, and covering ground under the building to prevent termite entry into the building, etc.
