Abstract
- In this paper, Button rock asphalt particle was directly added into hot asphalt mixture (HMA) to produced high modulus asphalt mixture (HMAM). In order to evaluate the performance properties of HMAM with BRA, dynamic compressive complex modulus (E*) test, rutting test and moisture resistance test were used to investigate HMAM with BRA and HMA with SBS modifier. Test results indicate BRA can greatly improve dynamic E*and rutting resistance of HMA compared with SBS modified asphalt mixture. Moisture resistance ability of HMAM with BRA has the same level with SBS modified asphalt mixture. Therefore, BRA particle can be used to produce HMAM, which have more superior performance properties than SBS asphalt modifier.
