不同高模量改性沥青高温性能及温度敏感性研究

Study on High Temperature Performance and Temperature Sensitivity of Modified Asphalt with Different High Modulus

为了探究不同类型高模量剂对沥青高温性能及温度敏感性能的影响,使用三种类型的高模量剂制备高模量改性沥青。分别对三种改性沥青进行DSR试验,同时采用复数指数法评价沥青的温度敏感性。结果表明,加入高模量剂可以改善沥青的高温性能和温度敏感性。

In order to explore the effects of different types of high modulus agents on the high temperature performance and temperature sensitivity of asphalt, three types of high modulus agents were used to prepare high modulus modified asphalt. DSR tests were carried out on three kinds of modified asphalt, and the complex index method was used to evaluate the temperature sensitivity of asphalt. The results show that adding high modulus agent can improve the high temperature performance and temperature sensitivity of asphalt.
