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

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.

An asphalt-cement concrete ('ACC') interlayer formed of a plant-mix material reinforced with aramid fibers, deposited at a thickness of at least one inch (1&#x2033;) over a Portland-cement concrete ('PCC') or ACC base, can extend the service life of a hot-mix asphalt (&#x201c;HMA&#x201d;) surface layer installed over the interlayer by retarding or preventing &#x201c;reflected&#x201d; cracks&#x2014;cracks in the surface layer that correspond to cracks, damage and irregularities in the PCC or ACC base. When the surface layer's useable life has expired, it can be removed and replaced, and the interlayer can continue to protect the new surface layer.

Asphalt cement concrete interlayer system for reflective crack relief

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.
