G4高速公路湖南耒宜段大修工程路面结构方案设计

摘要

This paper introduces the original variety of Leiyi Expressway pavement structure,traf-fic flow and pavement damage.According to the pavement structure specific,traffic flow and axle load disparity of the road,using a technical and economical comparison,the original continuous reinforced concrete pavement overlay asphalt concrete pavement structure,the original ordinary cement concrete and reinforced concrete pavement overlay continuously reinforced concrete composite pavement,milling and overlay single or bunk asphalt pavement layer on the original asphalt pavement,the original asphalt pave-ment overlay situ thermal regeneration after single and double bituminous surface layer structure.%介绍了耒宜高速公路原路面的多种路面结构与交通流量及路面损害情况，针对具体的路面结构与左右幅交通流量与轴载的悬殊差异，经技术经济比较，采用了在原连续配筋混凝土路面上直接加铺沥青混凝土路面结构；在原普通水泥混凝土与钢筋混凝土路面上加铺连续配筋混凝土复合式路面；在原沥青路面上进行铣刨加铺单层沥青面层与双层沥青面层、对原沥青路面进行就地热再生后加铺单层与双层沥青面层结构。
