摘　　要：针对青岛G308交叉路口车辙难处置的现状,在其大中修工程中采用了半柔性抗车辙路面技术。铺筑结果表明,通车12个月后半柔性路面车辙深度不超过1 mm,同时期铺筑的改性沥青AC-13路面已经出现2.5 cm车辙;半柔性路面路表构造深度在0.7~1.0 mm,抗滑性能优异;半柔性路面渗水系数在2 mL/min以下,低于普通沥青路面测试结果。In view of the current situation of difficult rutting treatment at G308 intersection in Qingdao,the semi flexible rutting resistant pavement technology is adopted in its large and medium maintenance project.The paving results show that the rut depth of semi flexible pavement is not more than 1 mm after 12 months of opening to traffic,and the modified asphalt AC-13 pavement paved in the same period has appeared 2.5 cm of rut;the semi flexible pavement surface structure depth is between 0.7~1.0 mm,with excellent skid resistance,and its water permeability coefficient is below 2 mL/min,which is far lower than the test results of ordinary asphalt pavement.
