不同工艺下高模量改性沥青性能研究

Study on properties of high modulus modified asphalt under drent processes

分析了直溜和氧化两种工艺下的高模量改性沥青的感温性能以及PG分级,同时进行了沥青混合料的高温抗车辙、水稳定性和低温抗裂试验,得出氧化工艺可更好地改善沥青及沥青混合料的性能。

This paper systematically analyzes the temperature sensitive performance and PG classification of high modulus modified asphalt under two processes of straight running and oxidation.At the same time,the high temperature rutting resistance,water stability and low temperature crack resistance tests of asphalt mixture are carried out.It is concluded that the oxidation process can better improve the performance of asphalt and asphalt mixture.
