(5) According to the Asphalt Recycling and Reclaiming Association, the practical limit for hot mix recycling in a batch plant is 20 percent RAP, although up to 40 percent RAP can be used. However, as high as 50 percent RAP has been used if the moisture content of the RAP is minimal and the RAP is fed to the plant at the ambient temperature.
