摘　　要：为了进一步研究路面裂缝与碎石基层材料的关系,首先就级配及成型方法对混合料性质的影响进行了广泛研究.采用上置式表面振动法与重型击实法对比,提出碎石材料较好的级配和成型方法,以期指导施工,减少路面的裂缝,延长路面使用寿命.The influence of grading and forming method in mixed material nature was studied so that the relation between pavement crack and crushed stones basic level mix material is further studied. And after comparison of surface vibrating method and heavyduty compact method, the quite good grading and forming method were adopted so that it can direct construction, reduce the pavement crack, prolong service life of the pavement.
