Paper Title:
Classification of Coarse Recycled Aggregate Used in Asphalt Concrete
  Abstract

Two classification methods for coarse recycled aggregate used in asphalt concrete were investigated in this paper, respectively classifying by coarse recycled aggregate properties and asphalt concrete properties. When classifying by coarse recycled aggregate properties, coarse recycled aggregate was classified into three types by the apparent specific gravity, water absorption, crushed value, Los Angeles abrasion value and brick content of coarse recycled aggregate. When classifying by asphalt concrete properties, coarse recycled aggregate was used to prepare asphalt concrete; and coarse recycled aggregate was classified into three types by the optimum asphalt content ratio (ROAC), theoretical maximum specific gravity ratio (RTMSG) and indirect tensile strength ratio (RITS) of asphalt concrete containing coarse recycled aggregate. The proposed classification criterions of the two classification methods were respectively given.
