Abstract
A method for converting a fiber reinforced composite material into a softening or recycling agent or product for hard asphalt or bitumen may include contacting a fiber reinforced composite material with a solvent, and converting at least some of the fiber reinforced composite material into a liquid product. The softening step may include, contacting the hard asphalt with the liquid product to produce a softened or rejuvenated asphalt. The fiber reinforced composite material may include a solid organic thermoset material and fibers. The hard asphalt may be obtained by petroleum refining, polymer modification or field aging.
