摘要/Abstract

摘要： 为提高胶粉改性沥青中胶粉掺量，加大废旧胶粉利用率，针对目前胶粉改性沥青中胶粉掺量较低问题，优化胶粉改性沥青制备工艺，制备超高掺量（40%）胶粉改性沥青。采用三大指标、TFOT试验和PAV试验研究超高掺量胶粉改性沥青基本性能与老化性能；基于DSR试验和BBR试验确定超高掺量胶粉改性沥青PG分级性能，采用拉伸试验评价超高掺量胶粉改性沥青黏韧性，通过TGA试验、荧光显微镜试验和SEM试验揭示超高掺量胶粉改性沥青的微观性能。结果表明：超高掺量胶粉改性沥青180 ℃旋转黏度低于4.0 Pa·s，其低温抗裂性和抗老化性能均优于常规掺量胶粉改性沥青；超高掺量胶粉改性沥青高温抗车辙性略有下降，但疲劳极限温度低于常规掺量胶粉改性沥青，确定其性能等级为PG 88-34；超高掺量胶粉改性沥青柔韧性占黏韧性比重为88.0%，是常规掺量胶粉改性沥青的2.1倍；180 ℃环境下，超高掺量胶粉改性沥青热稳定性最好；在保留一定弹性核心的基础上超量胶粉被降解为细小颗粒溶于沥青，决定了其宏观性能上良好的存储稳定性。

Abstract: In order to improve the content of rubber powder in rubber modified asphalt and increase the utilization ratio of waste rubber powder, aiming at the low content of rubber powder in rubber powder modified asphalt at present, the preparation process of rubber powder modified asphalt was optimized to prepare ultra-high content (40%) rubber powder modified asphalt. The basic properties and aging properties of ultra-high content rubber powder modified asphalt were studied by three indicators test, TFOT test and PAV test. Based on DSR test and BBR test, the PG grading performance of ultra-high content rubber powder modified asphalt was determined. The tensile test was used to evaluate the viscosity and toughness of ultra-high content rubber powder modified asphalt. TGA test, fluorescence microscopy test and SEM test were used to reveal the micro-properties of asphalt modified with ultra-high content rubber powder. The results show that the rotational viscosity of ultra-high content rubber powder modified asphalt is lower than 4.0 Pa·s at 180 ℃, and its low temperature crack resistance and aging resistance are better than those of conventional rubber powder modified asphalt. The high temperature rutting resistance of ultra-high content rubber powder modified asphalt decreases slightly, but its fatigue limit temperature is lower than that of conventional rubber powder modified asphalt, and its performance grade is determined to be PG 88-34. Flexibility of ultra-high content rubber powder modified asphalt accounts for 88.0% of the viscosity toughness, which is 2.1 times as much as that of conventional rubber powder modified asphalt. At 180 ℃, the thermal stability of asphalt modified with ultra-high rubber powder content is the best. On the basis of retaining a certain elastic core, the excess rubber powder is degraded into fine particles and dissolved in asphalt, which determines the good storage stability in macroscopic performance.
