Abstract

PURPOSE: The titled composition having improved softening in extremely hot period, fluidity, brittleness phenomena in cold period, galling phenomena, adhesiveness to aggregates, etc., obtained by blending a bituminous substance with finely powdered coal ash.
CONSTITUTION: A bituminous substance such as asphalt, cut-back asphalt, tar, a mixture of asphalt and tar, etc., an improved bituminous substance obtained by adding rubber, elastomer, synthetic resin, etc. to the bituminous substance is blended with 5W50wt% based on nonvolatile component of bituminous substance of finely powdered coal ash while being pulverized, to form a stable composite material. The addition of a cationic type surface active agent as a peeling inhibitor improves dispersibility of coal ash.
