摘　　要：结合某高速公路工程,对水泥-石灰-干渣半刚性基层材料路用性能进行研究。选择原材料,通过抗压强度、疲劳强度和抗弯拉强度确定水泥-石灰-干渣半刚性基层材料的掺量,最佳水泥、石灰、干渣掺量分别为4%、3%、70%,最后检测水泥-石灰-干渣半刚性基层路段平整度和压实度发现该路段具有较好的路用性能。The road performance of cement-lime-dry slag semi-rigid base material was studied in connection with an expressway project.The content of cement-lime-dry slag semi-rigid base material is determined by compressive strength,fatigue strength and flexural tensile strength.The optimal content of cement,lime and dry slag is 4%,3%and 70%,respectively.Finally,the flatness and compactness of cement-lime-dry slag semi-rigid base section are tested,and it is found that the section has good road performance.
