Generally cold milling machines crush the RAP in-place and used to break up the pavement material so that it can be loaded into a truck for crushing at a central plant. The amount of pavement material degradation by cold milling is a function of the aggregate top-size and gradation of the HMA pavement.

Rap crushing is to reduce the RAP to the maximum acceptable particle size. RAP crushers are applied for this process in central plants. Different types of crushers are available, for example, Jaw crushers and Horizontal impact crusher, hammer mill crusher. Hammer mill crusher are most widely used in asphalt recycling.
