The Present disclosure is related to hot-mix asphalt ('HMA') for asphalt cement concrete (“ACC”) pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (“RAP”, and including recycled asphalt shingles [“RAS”]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.

Methods and compositions to increase performance of asphalt cement concrete comprising recycled asphalt pavement

Reinforcing filaments or fibers, such as aromatic polyamide (aramid) fibers, can be reliably measured and consistently mixed into asphalt cement concrete by soaking the fibers in a wetting agent, then severing them to a desired length, and mixing the segments with other ACC ingredients. The wetting agent holds the fibers together loosely, so they can be distributed more uniformly throughout the ACC without clumping. The wetting agent soaks into the ACC mixture and/or evaporates, leaving the reinforcing fibers behind.

Additive to improve properties of asphalt cement concrete and method of manufacturing thereof

The Present disclosure is related to hot-mix asphalt ('HMA') which open new price/performance areas to asphalt cement concrete (“ACC”) pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (“RAP”, and including recycled asphalt shingles [“RAS”]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.

Embodiments of the invention are amendments to hot-mix asphalt ('HMA') which open new price/performance areas to asphalt cement concrete ('ACC') pavement. Equivalent-performing pavement may be made at lower cost, or higher-performing pavement may be made at equivalent-to-prior-art cost. The amendments, recycled asphalt pavement (&#x201c;RAP&#x201d;, and including recycled asphalt shingles [&#x201c;RAS&#x201d;]), and reinforcing fiber (aramid fiber) may be adjusted as described herein to achieve a desired price/performance target.
