固化剂稳定粉土路面基层材料的路用性能研究

通过对两种不同固化剂在不同剂量情况下稳定粉土的强度、刚度、水稳定性、冻融稳定性及干缩、温缩等性能的实验研究,分析了水泥基及石灰基的两种固化剂在相同配合比及同一种固化剂不同配合比或不同龄期情况下的路用性能的变化规律,得出了适当配合比的固化剂稳定粉土能够满足路面基层材料的要求,并结合使用性能提出了实际应用时应重点注意的问题,为工程应用做了一定的准备。

Research on Road Usage Performance of Base Materials for Silt Pavement Stabilized- Curing Agent

By experimental research on the strength,rigidity,waterability,freezethaw stability along with performance of dry shrinkage and warm shrinkage of the silt stabilized by both kinds of curing agents under different dose,the paper analyzes changing law for road usage behavior of both curing agents for cement and line bases under the identical proportionings as well as the different proportioning or age for the same curing agent,having obtained the requirements to be capable of satisfying the base naterials for pavement by silt stabilized by curing agent with adequate proportioning.In the light of service performance,it proposes issues which should be noticed as applying it in the practice.
