对水泥砼路面的表面抗滑性能研究

Research on Surface Anti-slide of Concrete Pavement

通过对水泥砼路表面进行不同处理的施工工艺试验路检测分析得出,原水泥砼路面质量验收中提出的单一要求抗滑构造深度值(TD)的检测指标,已不能准确地反映采用机械切纹的水泥砼路表的实际抗滑性能,而以采用TD检测与摩擦系数的双控检测指标为宜,且摆式摩擦系数测定值误差过大,也难以准确地反映水泥砼路表的实际抗滑性能。

As the examination of concrete pavement that has been disposed by various constructing technics shown,the checking index of single anti-slide structural depth value(TD)that was put forward in former concrete pavement examination,can′t reflect the actual anti-slide character of concrete pavement using machine cutting. Furthermore,the error of pendulumlike friction coefficient value is too high,and can′t reflect in like manner. However,the double controlling index of TD and friction coefficient is appropriate.
