环氧沥青混合料低温抗裂性能研究进展

Advances in the Low-temperature Anti-cracking Performance of Epoxy Asphalt Mixture

针对大跨径钢桥桥面铺装层易出现低温裂缝这一现象,总结了国内外关于环氧沥青混合料低温抗裂性能的研究进展,分析了环氧沥青铺装层低温开裂的影响因素,并据此提出改善环氧沥青混合料低温开裂性能的建议,并对工程实际应用中出现的低温开裂问题提供解决问题的思路。

The pavement layer of long - span steel bridge deck is easy to crack at low temperature. In order to solve this problem, the domestic and overseas research on the low - temperature anti - cracking performance of epoxy asphalt mixtures is summarized, and the factors of epoxy asphalt pavement cracking are ana- lyzed. Accordingly, suggestions are raised to improve the performance of epoxy asphalt mixture at low tempera- ture, which provide ideas for solving the low - temperature cracking problem in the engineering application.
