A composite material and process for forming composite material. The composite material comprises a quantity of plastinated plant distributed within a matrix material. The process comprises separating a plant material into plant fibers plastinating the plant fibers and combining the plastinated plant fibers with a matrix material. The plant fibers may be selected form the group consisting of bamboo, hemp and flax. The plant fibers may be formed by crushing a portion of a plant. The matrix material may comprise Polyethylene Terephthalate (PET). The PET may be shredded and heated. The heated composite material may be formed into rebar and be arranged in a pattern within a concrete slurry.

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.
