黄石高速公路大中修方案确定

Determination of large and middle schemes for Huanghua to Shijiazhuang expressway

随着时间的推移、交通量的迅猛增长,黄石高速公路出现了横、纵向裂缝,车辙、抗滑不足等病害,导致行车安全性降低。考虑到路面结构强度优良、各路段路面结构的差异,根据各路段实际情况,提出不同的段落分别采用就地热再生和4 cm罩面两种不同的处理方案。供同类工程参考。

As time goes on and traffic increases fast,damages like transverse and longitudinal cracks,rutting,and deficient skid-resistance appear in Huanghua to Shijiazhuang expressway,which influence the security of driving.In consideration of strength of pavement structure and the differences from one structure of road section to another,based on the practical situation of each section,the paper proposes two different schemes that are in-place hot recycling and 4 cm overlay used in different road sections which provide a reference for similar projects.
