Abstract
An asphalt pavement material comprising an aggregate mixture of asphalt, gravel, sand and a pelletized composite of recycled rubber and thermoplastic material. The pelletized composite has a uniform size, smaller than the gravel and larger than the sand and is configured to fit within interstitial voids between the gravel. Sufficient pelletized composite is added to the asphalt pavement and mineral aggregate mixture (replacing mineral aggregate of comparable size) to substantially fill void spaces between the gravel.
