摘要
首先分析了桃夭门大桥的工程特征及其使用的环氧沥青混合料特点,然后对高粘SMA-5的高温稳定性、低温抗裂性能以及抗水损害性能进行分析。结果表明,细粒式高粘SMA-5沥青混合料的60℃动稳定度为8580次/mm;冻融劈裂强度比为92.12%;低温破坏应变为3100με;残留稳定度为93.31%;高粘SMA-5具有良好的路用性能,能够与钢桥桥面紧密粘结,达到了良好的应用效果。
Firstly, epoxy asphalt mixture. and resistance to water the article analyzed the characteristics of Tao Yao - men Then it analyzed the high temperature stability of viscous damage performance. The results show that： The fine- Bridge and the characteristics of SMA -5, the cracking resistance grained dynamic stability viscous SMA -5 asphalt mixture at 60℃ is 8580 times/mm; The freeze -thaw splitting strength ratio of 92.12% ; and the low failure strain is 3100μs; the residual stability is 93.31%; the high viscosity SMA-5 has a good pavement performance; it can be closely bonded with the steel bridge and achieve a good application effect.
