半柔性抗车辙路面在昆山道路交叉口的应用

Application of Semi-flexible Anti-rutting Pavement in Kunshan Municipal Crossroads

文章针对昆山市机场路交叉路口车辙难处置的现状,在其车辙维修养护工程中进行了半柔性抗车辙路面技术的试用。试验段铺筑结果表明,经过半年的通车,半柔性路面没有车辙;半柔性路面试验段弯沉值比原沥青路面弯沉值降低约38.9%,较大幅度提高路面整体承载能力;半柔性路面路表构造深度在0.82 mm~0.98 mm之间,抗滑性能优异。

In response to the current situation of difficult handling of ruts at the intersection of Airport Road in Kunshan City,a semi flexible anti rut pavement technology was tested in its rut maintenance and repair project.The paving results of the experimental section indicate that after six months of operation,there are no ruts on the semi flexible road surface;The deflection value of the semi-flexible pavement test section is reduced by about 38.9%compared to the original asphalt pavement,significantly improving the overall bearing capacity of the pavement;The construction depth of the semi flexible pavement surface is between 0.82~0.98mm,with excellent anti slip performance.
