摘要
以水泥稳定土、水泥稳定碎石和石灰-粉煤灰稳定碎石三种典型半刚性基层材料为例,从材料的组成和配合比设计方面考虑,研究了对材料抗冲刷性能影响较大的几个因素,包括胶结料的含量及比例、胶结料的等级、细集料含量、混合料结构类型、养生龄期、含水量、压实度。研究结果能为今后半刚性基层材料的选择和配合比设计提供一些参考。
Taking 3 typical types of semi-rigid base materials （cement-stabilized soil, cement-stabilized macadam and lime fly-ash stabilized macadam） for example, considering material＇s composition and design of mix proportion, several influencing factors which have major effect on erosion-resistance performance of these materials are studied. These influencing factors include content, proportion and grade of binder, fine aggregate content, mix structure type, curing age, moisture content and compactness. The result can be a reference for the choice and design of semi-rigid base materials in the future.
