摘　　要：为了综合评价使用厂拌冷再生技术的沥青路面使用厚度、使用层位以及使用效果,采用ABAQUS有限元数值模拟和现场实际调查相结合的方法进行研究。结果表明:厂拌冷再生材料作为下面层厚度较薄时路面易发生破坏,而作为联接层时整体路面状况较好;根据现场调查得到厂拌冷再生材料在使用初期强度未形成,且抗水损害能力差,在施工过程中建议加铺封层进行防水,而其作为联接层可以有效吸收和消散应力。In order to synthetically evaluate the thickness of asphalt pavement,the use layer and the use effect of the central plant cold recycling,this paper studied these with the method of combining the ABAQUS finite element numerical simulation and the actual field investigation. The results show that asphalt pavement prone to damage when central plant cold recycling materials with a thinner thickness are used as the lower layer. But the overall pavement condition is better when it is used as the connection layer; According to the field investigation,the strength of cold mix recycled materials was not formed at the initial stage of operation,and the ability to resist water damage was poor. In the course of construction. Therefore,it is suggested to add the seal for waterproofing during construction,it acts as a connecting layer to absorb and dissipate stress effectively.
