某水泥混凝土路面强度的钻芯取样法检测

Drill core sampling method for strength of cement concrete pavement

采用钻芯取样方法,统计分析了全部41个芯样的直径与厚度,对其中部分芯样进行了室内劈裂强度试验,并计算了其芯样劈裂强度值,反算了水泥混凝土板的弯拉强度,以准确评价老旧水泥混凝土路面强度指标。

Drill core sampling method was used and conducted statistical analysis of the diameter and thickness of all 41 core samples. Indoor splitting strength test was carried out for some core samples, and the core sample splitting strength was calculated, and the bending strength of ce-ment concrete slab was calculated, in order to evaluate the strength of an old cement concrete pavement.
