摘　　要：沥青面层之间以及与基层之间的粘结状态对路面力学响应的影响较大。本文通过室内剪切试验和拉拔试验分析胶粉改性沥青、环氧改性沥青和高分子聚合物改性沥青在不同粘层油洒布量下的抗剪强度和拉拔强度,并与B ISAR软件得到的理论计算值进行比较,得到3种粘层油稳定性的差异以及最佳洒布量。The interfacial contact between asphalt layers and bases gives the mechanic response of asphalt concrete pavement greater impact. The rubber power modified asphalt, epoxy modified asphalt and polymer modified asphalt are analyzed through laboratory shear test and pull-out test which are to gain changes of shear strength and tensile strength with different spilling contents. Last, compared with theoretical values calculated by BISAR software, the difference of the three kind of adhesive layer oils and the optimal spilling contents are attained.
