TG 6 of Rilem TC - SIB : Classification of RAP 1 / 14 Classification of Recycled Asphalt ( RA ) Material

Use of recycled asphalt pavements (RA) in pavement rehabilitation processes is continuously growing as recycling techniques, such as cold recycling (CR), are being utilized in increasing magnitude. The focus of this paper is on developing a state of the art and state of the practice summary of processes used for classification of RA. A variety of topics were explored through an exhaustive literature search, these include RAP production methods, definition of RA materials, stockpiling practices and industrial operations. This paper was developed through efforts of cold recycling task group (TG6) of RILEM Technical Committee on Testing and Characterization of Sustainable Innovative Bituminous Materials and Systems (TC-SIB).
