基于旋转压实成型方法的泡沫沥青冷再生配合比设计

Mix ratio design of foamed asphalt cold recycling based on rotary compaction forming method

通过旋转压实成型方法进行泡沫沥青冷再生配合比设计,采用旋转压实仪成型泡沫冷再生试件,放置一定温度烘箱养生至规定时间,通过测试试件空隙率、干劈强度与干湿劈裂强度比确定最佳含水量与最佳泡沫沥青用量,通过冻融劈裂强度比与车辙试验验证混合料路用性能,完成配合比设计过程。

The mixture ratio design of foamed asphalt cold regeneration is carried out by the method of rotary compaction.The splitting strength ratio determines the optimum water content and the optimum amount of foamed asphalt.The road performance of the mixture is verified through the freeze-thaw splitting strength ratio and the rutting test,and the mix ratio design process is completed.
