稀土改性沥青路面低温养护新材料探讨

Discussion of New Maintenance Material of Modified Asphalt Pavement with Rare Earth in Low Temperature

从稀土冷补材料的原理及配置技术、稀土冷补材料的性能特点、冷补材料的生产与应用、不同类型的沥青混合料性能比较以及经济效益、社会效益等方面,对稀土改性沥青路面低温养护新材料进行了探讨。实践证明:稀土改性沥青路面低温养护新材料具有初始强度高、抗水性强、和易性与压实性好、贮存稳定、成型后路用性能优良等优点,应用于沥青路面的修补,取得了良好的效果。

The low temperature maintenance material of rare earth modified asphalt pavement is discussed from rare earth cold repair principle, composition, characteristics, production and application, and also from comparison of various asphalt mixture and economic, social benefits. The practice proves that the new material has advantages of high initial strength, good water resistance, good workability, easy compaction, stable storage, better pavement performance, etc. The application to asphalt pavement repair is getting better effects.
