摘　　要：通过室内试验分别对常规沥青和改性沥青的技术指标进行测定,对沥青混合料抗磨耗性能、高温抗车辙性能、低温抗裂性能进行了试验分析。试验结果表明:随着改性剂剂量的增加,沥青针入度、软化点、延度均有所改善;微表处沥青混合料抗磨耗性能、抗车辙性能、低温抗裂性能优于常规沥青混合料,具有优越的路用性能,可以延长路面的使用寿命。Through laboratory experiment, the technical indexes of conventional asphalt and modified asphalt are tested, and the anti-wear performance, high-temperature anti-rut performance, low-temperature anti-cracking performance of the asphalt mixture are analyzed. The results show that with the modifier increasing, penetration, softening point and ductility of asphalt are all improved. Because the anti-wear performance, anti-rut performance and anti-cracking performance of micro-surfacing asphalt mixture are better than the conventional asphalt mixture, microsurfacing mixture has good road performance, and can effectively extend the service life of pavement.
