Abstract
Abstract An improved asphalt emulsion composition comprises an oil phase having minor amounts of gilsonite and naphtha and a major amount of asphalt, and a water phase having water and a small amount of a cationic emulsifying agent, wherein the ratio between the oil and water phases is between about 1:1 and 2:1 by weight respectively, the asphalt having a distillation residue penetration of less than 40 dmm at 77° F (25° C).
