Asphalt Pavement Recycling - California

Asphalt Pavement. While recycled asphalt pavement was not reported separately in these data, generation of "inert solid waste," which consists of concrete, asphalt, dirt, brick and other rubble, was conservatively estimated at 8.2 million tons. The estimated recycling rate for inert solid wastes was 57 percent; the remainder was disposed of.

Oct 31, 2014  Reclaimed asphalt pavement (RAP) is a term given to removed and/or milled pavement materials containing asphalt and aggregates. This material is obtained from recycling the existing flexible pavements which have reached the end of their design life or shown excessive cracking. The use of RAP has grown widely reducing the use of virgin material thus helps to conserve the natural resources.

Dec 11, 2007  Every year Hot Mix Asphalt (HMA) roadways are rehabilitated by milling the existing roadway and replacing the milled portion with new HMA. As a result of this practice, a tremendous amount of reclaimed asphalt pavement (RAP) is created. The Federal Highway Administration estimates that 100 million tons of HMA is milled each year (MAPA, 2007).
