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.
