Hot mix recycling is the process in which reclaimed asphalt pavement materials are combined with new materials, sometimes along with a recycling agent, to produce hot mix asphalt mixtures. Just as in the case of conventional HMA, recycled mixtures must be designed properly to ensure proper performance.

Recycled hot mix asphalt mixtures also generally age more slowly and are more resistant to the action of water than conventional hot mix asphalt. (See references 5,6,7,8,9,10, and11.) The maximum limit for RAP content in RHM produced in conventional hot mix asphalt batch plants is widely considered to be 50 percent, limited by both the heat capacity of the plants and gaseous hydrocarbon emissions.
Apr 13, 2020 · The process to create a limited supply of hot mix asphalt begins with asphalt millings (recycled asphalt). For the past several years the City of Muscatine has required contractors on street projects to separate the asphalt, concrete, bricks, and dirt as they remove old pavement.
