摘　　要：根据对碎石基层混合料中的细集料和粗集料的研究结果,选择45:15的骨架结构,泰波指数分别为0.45和0.7的细集料,按体积法的设计原则,对细集料对粗集料的填充进行了研究,通过实验并结合工程实际给出了填充系数。According to the study on coarse aggregate and fine aggregate in crushed stone base mixed materials, the frame structure 45：15 was selected, and Talbol indexes of fine aggregates were respectively 0.45 and 0.7. Based on the design principles of volume method, the effects of stuff coefficient on coarse aggregate were studied, and proper stuff coefficient was given through experiments and engineering practice.
