摘　　要：对朱圩子互通立交原桥面铺装病害类型及成因进行调查分析,提出了相应的养护方案并从施工难易程度、可操作性等各方面进行对比分析,确定可行方案及相关技术要求,同时分析了沥青混合料添加抗车辙剂前后的压实特性,通过汉堡轮辙试验对其高温稳定性及水稳定性能进行对比验证。This paper mainly investigated cataloges of disease occurred in Zhuxuzi interchange bridge deck and analysed the course of formation. The corresponding maintennace countermeasure and technical request are put forward from thinking the workability, maneuverability factors, meanwhile, compaction characteristics, high temperature stability and moisture stability of asphalt mixture modified by rutting resistance additive are tested by using the Hamburg Wheel -tracking Test.
