沥青路面大修路面结构方案确定的思想

On thought of overhaul roadbed structure scheme of asphalt roadbed

对沥青路面大修时路面结构方案的合理确定方法进行了研究,提出了以分界弯沉值作为评判标准确定大修路面结构方案的方法,并以一个高速公路大修实例演示了分界弯沉值的计算方法,以供参考。

The paper researches the identifying methods for the roadbed structural scheme of the overhaul asphalt roadbed, points out the meth- ods to identifying the overhaul roadbed structural scheme by taking the dividing line deflection value as the evaluation standard, and displays the calculation methods for the dividing line deflection with the expressway maintenance, so as to provide some reference.
