摘要
对胶粉改性沥青及其混合料进行了一系列室内试验研究,包括不同掺量的胶粉改性沥青的技术性质试验、胶粉改性沥青混合料的高温车辙试验、浸水马歇尔试验和低温弯曲破坏试验。研究结果表明:胶粉能改善沥青的高、低温性能、感温性能和抗老化性能,而且能提高沥青混合料的高温稳定性、水稳定性和低温抗裂性。
A series of laboratory tests of rubber powder modified asphalt and its mixture were made. These included different content rubber powder modified asphalt technical property test, rubber powder modified asphalt mixture rutting test at high temperature, retained stability test, bend test at low temperature. The results showed that rubber powder can improve the performance of asphalt at high-temperature and low-high temperature, temperature susceptibility and anti-aged performance, and it can improve the performance of asphalt mixture at high temperature, the capacity of moisture-resistance damage and low temperature anti-cracking performance.
