摘　　要：应用战略公路研究计划SHRP方法对3种改性沥青的路用性能进行了评价,分别从高温稳定性、中温耐疲劳性和低温抗裂性3个方面进行了分析。结果表明,复合改性沥青具有良好的高温稳定性、耐疲劳性和抗裂性,其他路用指标达到了一定的路用要求。The strategic highway research program ances of three kinds of modified asphalts. The stability, ture, middle - temperature and low -temperature were of the high - temperature stability, anti - fatigue and anti and the other indexes could achieve the requirements of （SHRP） was used to evaluate the pavement perform- anti - fatigue and anti - cracking at high - tempera- analyzed. The results indicated that the performances - cracking of composite modified asphalts were good, service.
