Recycled Asphalt Pavement (RAP) Systems

With increasing energy costs and reduced availability of virgin materials, the addition of Recycled Asphalt Pavement (RAP) into the asphalt mix is becoming a very important factor for consideration by asphalt specifiers and producers alike. For many years Parker Plant has been designing solutions and overcoming the difficulties associated with the introduction of RAP to achieve more economical and environmentally acceptable methods of asphalt production. Cold RAP in the ratio 1:10 can be introduced directly into the hot elevator or a higher ratio of 1:4 can be achieved by adding directly into the mixer, either volumetrically or by weight, using a moisture evacuation system integrated within the mix cycle control. Systems for the introduction of RAP can be designed for retrofitting into existing asphalt plants.
