提高沥青路面抗水损害能力措施方法对比研究

Comparison study on measures to improve water damage resistance of asphalt pavement

改善沥青路面的抗水损害性能,对提高沥青路面的使用质量具有重要的意义。通过对一定浓度的消石灰处理石料表面以及沥青中掺加抗剥落剂技术制备的沥青混合料进行水稳性能测试对比分析,结果显示:与基质混合料相比,消石灰处理技术以及掺加抗剥落剂技术都能够提高混合料的抗水损害能力,前者提高14%,后者提高18%,说明后者效果更佳。但是,从力学的角度分析,用消石灰处理的改善效果优于抗剥落剂的应用技术。

Improving the water damage resistance of asphalt pavement has a great significance to improve the quality of asphalt pavement.Through water stable performance testing comparative analysis of asphalt mixture prepared by adding anti-stripping agent in the surface of a certain concentration of hydrated lime processing stone and asphalt,the results showed that: compared with the substrate mixture,hydrated lime processing technology and mixed with anti-stripping agent technology both can improve the water damage resistance of mixture,the former increased by 14%,the latter increased by 18%,the latter is better.However,from a mechanical point of view,the improvement effect of hydrated lime treatment is better than the anti-stripping agent technology.
