Asphalt Cement Concrete Interlayer System for Reflective Crack Relief

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″) over a Portland-cement concrete (“PCC”) or ACC base, can extend the service life of a hot-mix asphalt (“HMA”) surface layer installed over the interlayer by retarding or preventing “reflected” cracks—cracks in the surface layer that correspond to cracks, damage and irregularities in the PCC or ACC base.
