摘　　要：以层间抗剪性能为设计指标,进行橡胶沥青碎石封层不同结构、沥青撒布量、碎石撒布量等设计参数的确定。通过合理设置正交试验,在大量减少实验量的基础上,得出不同结构下的橡胶沥青碎石封层均具有良好的层间结合效果,但双层封层的效果要更优。本研究不但确定了不同结构橡胶沥青碎石封层的设计参数,而且可为橡胶沥青碎石封层规范的制订提供很好的数据参考。Taking shearing strength at intersection as the design objective,design parameters like different structures of rubber asphalt chip seal,asphalt spreading volume,chip spreading volume and so on are determined.Through reasonably setting up orthogonal test,basing on reducing a large number of test,good combination effect at intersection of rubber asphalt chip seal under different structures is obtained. But the effect of double- layer seal is superior. Not only the design parameters of rubber asphalt chip seal with different structures are determined,but also good data reference for the establishment of rubber asphalt chip seal standard are provided.
