In order to enhance modulus, the design of materials, structural combination and construction technology of the graded broken stone base were studied.
为了提高路面结构中级配碎石基层的回弹模量，通过材料设计、路面结构组合设计和施工工艺设计，对级配碎石基层的使用性能进行了研究。
Results indicate that the modulus can be improved largely by using above three methods in the design and construction of graded broken stone base.
综合考虑以上因素的试验路模量反算结果表明：级配碎石的强度有大幅度提高。
