摘要
选用60℃、75℃车辙试验和动态模量试验来研究外掺剂高模量混合料的高温稳定性能。试验结果表明,添加高模量外掺剂后混合料高温性能得到了显著提高;随着温度的增加,外掺剂对混合料高温性能的提升幅度不断增大。这说明越是在高温环境下,高模量混合料抵抗车辙病害的能力越强。
The rutting test and dynamic modulus test at 60℃ and 75 ℃ were done to study the high temperature performance of high-modulus additive modified asphalt mixture. The experimental results show that： the high temperature performance of the mixture was significantly improved after adding high-modulus additive; as the temperature rises, the high temperature performance improves a lot. It shows that at higher temperature, the ability of high- modulus mixture to resist rutting disease is stronger.
