摘要: Quick setting, anionic bitumen emulsion compositions, suitable for road paving, recreational surfaces, etc., are formulated by emulsifying the bitumen in water with an ammonium or alkali metal salt of a hydrocarbon-substituted sulfuric, sulfonic, phosphoric or phosphonic acid emulsifier, mixing the emulsion with a fine aggregate and, prior to spreading the aggregate emulsion mixture, introducing an alkaline earth metal set initiator. The resulting composition rapidly breaks to a hard cohesive structure, so as to permit early use by traffic.
