摘　　要：针对沪武(上海—武汉)高速公路太仓北枢纽至董浜枢纽段由双向六车道扩建为双向十车道的扩建工程,开展了既有路面技术状况评估、交通量分析和拼接结构设计研究。首先,基于现状路面的表观性能、结构性能和材料性能综合分析,评价既有路面的适用性;其次,分析路段交通量特征并提出了适用于十车道高速公路的车道系数推荐范围;最后,针对路面排水及路面拼接的特殊需求,提出排水沥青混合料表面层结构和分层拼接台阶的设计方案。研究成果可为我国高速公路扩建工程提供参考。In view of the expansion project of the Shanghai-Wuhan Expressway from Taicang North Hub to Dongbang Hub,which involves widening the road from two-way six lanes to two-way ten lanes,a comprehensive study was conducted on the technical condition evaluation of the existing pavement,traffic volume analysis,and splice structure design.Firstly,the applicability of the existing pavement was evaluated based on a comprehensive analysis of apparent performance,structural performance,and material performance.Secondly,the characteristics of road traffic volume were analyzed,and a recommended range of lane coefficients suitable for ten-lane expressways was proposed.Finally,considering the special requirements of pavement drainage and splicing,the design scheme of surface layer structure and layered splicing step of porous asphalt mixture was developed.The research findings provide a reference for the expansion project of expressways in China.
