| 摘 要： | 采用ARAN9000多功能道路检测车测量路面平均断面深度(MPD),MK-6双轮横向力系数测试仪测得摩擦系数Mu-meter值,经换算得到横向力系数(SFC)。分别连续检测三公里橡胶改性沥青路面和SBS改性沥青路面,按照百米作为基本评价单元。使用横向力系数(SFC)表征路面抗滑性能时,SBS改性沥青路面为橡胶改性沥青路面的1.3倍;使用MPD表征抗滑性能指标时,橡胶沥青路面是SBS改性沥青路面的1.90倍。可见使用MPD表征路面抗滑性能有一定的适用条件,建议实测路面SFC反映路面抗滑性能。

| Abstract: | The average depth of texture （MPD） is measured by ARAN9000 automatic roadway machine. Sideway force coefficient （SFC） is measured by MK-6 double wheels＂ transverse force coefficient machine through conversion. Three kilometers of rubber asphalt and SBS modified asphalt pavement are measured separately and continuously, lO0m as the basic evaluation unit. SBS modified asphalt pavement is 1.3 times of rubber asphalt pavement when pavement skid resistance is characterized by SFC. The average value of MPD about rubber asphalt pavement is 1.9 times of SBS modified asphalt pavement. The result shows that there is some limitations when use MPD to characterize the skid resistance, so it is recommended to test skid resistance through testing SFC. |
