罗得岛交通运输部(RIDOT)在道路改建过程中处理带裂缝的路面通常采用铣刨加更换2.5~5cm的表面层的方法,然而路面仍然过早破坏从而造成RIDOT损失数百万美元。这项研究是为了探求把裂缝控制在表面层的方法,并根据不同的现场条件选择不同刚度和厚度的表面层进行分类,按照分类提供相应的解决方案。把面层下临界拉应变值作为引起路段开裂的控制指标。根据对许多罩面路段的观测可以看出RIDOT罩面厚度太薄也会出现裂缝。
RIDOT Department of Transportation (RIDOT) in the road reconstruction process with cracks in the road surface is usually used for milling and replacement of 2.5 ~ 5cm surface layer method, but the road is still premature destruction, resulting in RIDOT millions of dollars in losses. This study is to find ways to control cracks in the surface layer and to choose surface layers of different stiffness and thickness to classify according to different field conditions, and provide corresponding solutions according to classification. To the surface under the critical tensile strain value as a cause of road cracking control indicators. Based on observations of many covered sections, it can be seen that the RIDOT overcoat is too thin and cracked.
