ABSTRACT:
The present invention relates to mixing-grade, quick-setting, and slow-setting cationic aqueous bituminous emulsion-aggregate paving slurry seal mixtures. More particularly, this invention relates to paving slurry seal mixtures formed with cationic emulsions prepared by emulsifying bitumen (e.g. asphalt) in water with a cation-active emulsifier. The emulsifier is the product of the reaction of polyamines with certain fatty acids and rosins, and a quaternizing agent such as 2,3-epoxy-propyl-trimethyl ammonium chloride or 3-chloro-2-hydroxy propyl-trimethyl ammonium chloride.
