摘　　要：为了进一步研究碎石基层混合料的级配性质对路面破坏的影响,在规范范围内设计5种级配,采用了上置式表面振动压实成型法和重型击实法两种方法,对碎石基层级配混合料成型方法与混合料性质的关系进行了广泛的研究,从而得出结论,以便指导碎石基层混合料的施工。Five kinds of grading within the standard range were designed in order to furthe r study the effect of the grading for crushed stone mixture on pavement. Two met hods of up-laying surface vibratory compaction and heavy-duty compaction were ad opted to study the relationships between the molding methods of crushed stone mi xture and the properties of mixture. Some conclusions were drawn, which could pr ovide references for the construction of crushed stone mixture.

关 键 词：振动压实 重型击实 最大干密度
