摘　　要：通过在沥青中加入废旧橡胶粉,并对橡胶沥青和基质沥青进行对比试验,表明橡胶粉的加入可增大沥青黏度,改善低温柔韧性,提高弹性恢复能力。采取相同沥青用量和相同级配的橡胶沥青混合料和普通沥青混合料进行路用性能对比试验,表明橡胶粉的掺入可改善普通沥青混合料的高温性能、低温抗裂性能和水稳定性能。Through adding waste rubber powder in asphalt,and contrast test of rubber asphalt and asphalt matrix,suggests that the addition of rubber powder can increase the viscosity of asphalt,improve the flexibility at low temperature,improve the elastic recovery ability.The article take same asphalt dosage and graded rubber asphalt mixture and common asphalt mixture for road use performance contrast test,showed that the rubber,the mixed powder,can improve the performance of ordinary asphalt mixture at high temperature,low temperature crack resistance and water stability.
