Abstract
Disclosed is a medium set cationic bituminous emulsion comprising, relative to the emulsion: PA1 a. about 40 to 75% by weight asphalt; PA1 b. 0.25 to 5% by weight of a cationic emulsifier; PA1 c. 0.1 to 0.5% by weight of a nonionic water-soluble thickening agent; PA1 d. 0 to 8% of a low-boiling hydrocarbon; and PA1 e. water as a continuous phase of said emulsion to make up 100% by weight; wherein said medium set emulsion when combined with open-graded aggregate produces a mix which has a thick coating of emulsion on said aggregate surface and said mix is workable and results in minimum runoff.
