摘　　要：通过正交试验,找到二灰碎石各种材料的用量比例,主要是二灰内比、碎石比例和级配、水泥掺量等与结构强度、横缝出现情况的关系.并在基层条件不变的情况下,分析和讨论了沥青面层厚度对横向裂缝间距的影响.The mixture ratios mainly including the proportion of Lime and Fly-ash, aggregate and grading collocation and the cement parameter are found out through orthngonal experiment. The relationship between the ratios and construction strength as well as the cress cracks is put forward. Then the influences of the thickness of the asphalt pavement on cross cracks are an- alyzed and discussed.
