摘　　要：为了研究不同沥青混凝土加铺层结构延缓复合式路面反射裂缝的效果,采用沥青路面分析仪对四种沥青混凝土加铺层结构抵抗反射裂缝的能力进行了对比试验研究。试验结果表明:四种结构方案中,方案四的加铺层结构抵抗反射裂缝的能力最强;厚度相同时,橡胶沥青混凝土抵抗反射裂缝的能力优于SMA沥青混凝土;适当增加橡胶沥青应力吸收层能提高抵抗反射裂缝的能力;增加沥青加铺层厚度对延缓反射裂缝的作用显著。In order to study different effects of different asphalt concrete paving layer structures have on delaying reflective cracks in complex pavement, adopted asphalt pavement analyzer to implement comparative study on reflective cracks resistance capacity of four kinds of asphalt concrete paving layer structures. The result of the test shows that ： among four structure schemes, the paving layer structure of the fourth scheme has the best reflective cracks resistance capacity; when the thickness is the same, reflective cracks resistance capacity of rubber asphalt concrete is better than reflective cracks resistance capacity of SMA asphalt concrete ; appropriate increase of rubber asphalt stress absorbed layer may improve reflective cracks resistance capacity; increase in the thickness of asphalt layer has significant effect on delay reflective crack.
