摘要
道路路面工程验收时经常需要检测的一个参数就是路面构造深度,而电动铺砂仪检测路面构造深度就是常用的检测方法。由于路面构造深度的设计值通常都是一个较小值,而实际检测过程中铺砂砂带的模型与现行试验规程中的假定模型存在着一定的差异,这一差异对其检测结果的精度也存在着一定的影响。文章结合笔者自身的实践经验,对该试验方法中的假定模型及其计算公式进行优化并列举了相关推导过程。
In the acceptance of road pavement engineering,one of parameters usually needed to be tested is the pavement texture depth. The testing of pavement texture depth by automatic sand paving method is a common method. Due to the design value of pavement texture depth is smaller,there is a certain difference between the model of sand belt in the actual testing process and the hypothetical model in the current test specification,which also has a certain impact on the accuracy of the testing results. Combined with personal practical experience,this paper optimizes the hypothetical model and its calculation formula in the test method,and enumerates the relevant derivation process.
