Reclaimed asphalt pavement (RAP) is most often produced by milling an existing asphalt pavement and screening the material for use in a new asphalt mix or use as aggregate base. Asphalt recycling in South Africa is done by four methods: cold in-place recycling, cold in-plant recycling, hot in-place recycling, and hot in-plant recycling [55].
