Abstract
Asphalt emulsion compositions for use in priming a granular surface such as a road bed are provided. The asphalt emulsion comprises asphalt, an amphoteric emulsifier, and water. The asphalt emulsion priming composition may be used on road beds to prepare the road bed for paving. Application of the asphalt emulsion priming composition to a granular surface, such as a road bed, can provide several advantages, including reducing or eliminating dust generated by traffic on the granular surface.
