纵向摩擦系数在路面抗滑性能评价中的应用

为分析纵向摩擦系数在路面抗滑性能评价中的应用,首先研究了SAFEGATE摩擦系数测试车的组成及工作原理。通过选取高等级公路典型断面结构作为测试路段,采用摆式仪和SAFE-GATE摩擦系数测试车测定相应的摆值与纵向摩擦系数,回归出二者之间的相关关系式,据此得出路面设计和养护的纵向摩擦系数标准。最后选取典型道路路面,提出抗滑性能纵向摩擦系数的检测与分析方法。结果表明,利用纵向摩擦系数表征路面的抗滑性能是切实可行的。

Application of profile frictional coefficient in evaluation of pavement skid-resistant performance

To educe the application of profile frictional coefficient in the evaluation of pavement skid-resistant performance, the paper firstly studied the components and work theory of SAFEGATE test vehicle of frictional coefficient. By choosing high-grade highway typical section structure as test road, with pendulum apparatus and SAFEGATE test vehicle, the paper tested the corresponding British pendulun number and profile frictional coefficient, educed the correlativity relation between them, and put forward the profile frictional coefficient standard in pavement design and maintenance according to this. At last, the paper advanced the test and analysis method of profile frictional coefficient by choosing typical pavement. The results indicate that it is feasible to attribute the skid-resistant performance of pavement with profile frictional coefficient.5 tabs, 5 figs, 8 refs.
