C09D 3387
C09D 324
C09D 324
US Classification:
106502
Abstract:
Disclosed is a cationic bituminous emulsion comprising relative to the emulsion about 40 to 70% by weight asphalt, 0. 25 to 5% by weight of a cationic emulsifier, 0. 1-0. 5% by weight of a water-soluble thickening agent, 0-8% of a low-boiling hydrocarbon, and water as a continuous phase of said emulsion to make up 100% by weight. The emulsion is particularly useful for open-graded roads.

C09D 324
C09D 324
US Classification:
106502
Abstract:
Disclosed is a medium set cationic bituminous emulsion comprising, relative to the emulsion: a. about 40 to 75% by weight asphalt; b. 0. 25 to 5% by weight of a cationic emulsifier; c. 0. 1 to 0. 5% by weight of a nonionic water-soluble thickening agent; d. 0 to 8% of a low-boiling hydrocarbon; and 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.
