Abstract

A type of recycling agent was developed and its use for modifying used asphalt is described. The results show that the viscosity and three main properties of the aged asphalt were remarkably improved. With 5%–7% content of recycling agent, the main properties of recycled asphalt comported with China GB asphalt standard AH—70 and the recycled asphalt concrete could be used as high-grade highway. Furthermore, the recycling mechanism of the aged asphalt is discussed.

Keywords
