Hybrid structural polymer-binder composite construction and paving material

Abstract

A hybrid additive for use in construction materials such as asphalt and concrete is disclosed. The additive includes pellets formed of a plastic or polymer material, and one or more of fibers, pozzolans, nano-carbon tubes, glass, recycled asphalt shingles (RAS), liquid anti-strip, hydrated lime, rejuvenators, cementitious material, and ground tire rubber. Also disclosed are hybrid composite materials useful as paving and building materials, and methods of making the same. The hybrid additives were found to maintain the positive performance aspects of typical asphalt and concrete mixtures, while improving the performance of the mixtures by increasing bonding and strength within the mixture—and therefore increasing useable life and lowering costs.
