| 摘 要： | 针对某城市重载快速道沥青路面初期破坏情况和结构特点,对其分别进行了沥青面层厚度、路面芯样压实度、现场取板车辙实验、二灰碎石基层抗压强度实验,沥青面层抗剪强度贯入实验等实验研究,实验结果表明多项指标未达到规范要求。结合路面现场踏勘和分析得出道路施工各环节缺乏控制、材料差、低温施工和压实度不足是造成路面初期严重破坏的主要原...

| Abstract: | In view of the failure condition and structural characteristic of asphalt pavement of heavy-loaded express road in one city, measurement of thickness and compactness of asphalt surface layer,lab rutting test on field samples,uniaxial penetration test of asphalt core samples,compression strength test of lime-fly ash concrete were carried out.Some testing index results didn't satisfy the requirements of specification and design.Field investigation and test analysis show that lack of construction control in mu... |
