摘要
结合实际应用,分析了我国目前冷补料评价体系的不足之处;参考国外文献,开发设计了一套全面评价冷补料施工和易性、初期稳定性、耐久性、带水条件下施工能力等的试验方法。针对我国道路养护的实际需求,开发了一种价格适中、性能优异的冷补沥青混合料,具有全天候施工、高耐久等特点。将开发的冷补料应用于实际道路养护,效果良好。
Combined with practical application, the deficiencies of current cold patch evaluation system in China were analyzed. Refer to foreign literature, a set of test methods for cold patch was designed, inclu- ding the evaluation of workability, early - stage stability, durability and adhesion with the existence of water. A kind of reasonable - priced and high - performance cold patch asphalt for potholes was developed to meet the need of road maintenance. The new asphalt turned out to be good in practice.
