Abstract: In this paper,the maximum dry density, optimum moistUre content and the volume of CBR of different graded granular material are studied.Besides the grading type of the granular material, the maximum grain size,5 mm and 0. 074 mm possing content of the material are important which affect their strength.

Key words: graded aggregate, grain size, CBR

摘要： 本文通过对各种级配下无粘结碎石材料最大于密度、最佳含水量和CBR值的研究,提出了除级配类型(间断或连续)外,集料中最大粒径尺寸,通过4#筛(5 mm)和200#向下筛(0.074 mm)的含量将是影响该材料强度的重要因素.
