Abstract

A feasibility study was performed on a warm-mix asphalt mixture including aggregates coated by a chemically modified thermoset polymer. The thermoset polymer is a chemically synthesized with a carboxylic butadiene rubber and a silanol coupling agent. The adhesive strength was verified through the Dolly test and the Boiling test. The adhesive strength of the synthesized epoxy was at least 2-fold greater than that of a general epoxy. The boiling test verified that a superior coating effect maintaining greater than 90% of the epoxy-coated binder film. The mixture including the synthesized epoxy-coated aggregates resulted in 36% higher average indirect tensile strength compared to the general PG64–22 mixture. The rut deformation of the epoxy-coated mixture resulted in 2.1 times lower than the rut of the standard PG64-22 section through an accelerated field test.
