水稳基层循环冷再生混合料路用性能研究

On traffic performance of circulation cold regeneration mixture at cement stabilized base

通过正交试验,确定了水泥、膨胀剂、纤维的合理掺量,研究了采用外加剂后,循环冷再生水稳混合料的强度变化规律、收缩特性及其水稳定性,使循环冷再生的水稳基层混合料路用性能得到改善,从而实现水稳旧料的多次循环再生利用。

According to the orthogonal experiments,the paper identifies the reasonable mixture of cement,expansive agent,and fiber,researches the change rule,its shrinkage feature and water stability for the water stabilized cold regenerated mixture after adopting the additive agent,so as to improve the traffic performance of the mixture,and realize the multiple circulation regeneration and utility of the water stabilized materials.
