Abstract
Reaction products of polyamines with certain polycarboxylic acid anhydrides are disclosed which give emulsions capable of producing medium set mixing grade asphalt emulsions, rapid set asphalt emulsions, and quick set slurry seal emulsions. Solventless asphalts as well as asphalts containing up to 15% by volume of a hydrocarbon oil can be used for emulsification.
