| 摘 要： | 水泥稳定砂砾以其强度高,板体性好以及一定的水稳定性和耐久性,广泛应用于公路路面基层,但也存在一定的抗冻性问题。以半刚性基层材料水泥稳定沙砾为研究对象,在总结国内外研究成果的基础上,通过室内试验确定不同级配的水泥稳定砂砾在不同含水量、不同温度下、经冻融循环后的耐久性。对水泥稳定砂砾的低温性能进行比较,以确定保证半刚性基层材料水泥稳定砂砾强度的最佳配合比,以期指导工程实践。

| Abstract: | Cement stabilized gravel is widely used in highway pavement base due to its high strength,good plate body and certain water stability and durability.But it also has some frost resistance problems.In this study,semi-rigid base material of cement stabilized sand was taken as research object.Based on the summary of research results both domestic and abroad,the durability of cement stabilized gravel under different water content and different temperature after natural freeze-thaw cycle was determined by indoor ... |
