旧路改扩建项目中,对旧路检测与评定是项目设计及研究工作的基础。一般检测方法是采用多种手段对全线检测,但这种检测方法针对性不明显,需要耗费较大的人力和物力。因此本文提出了典型路段的检测方法,在对路面进行数项全线检测的基础上,挑选病害较为典型的路段选用多种手段进行进行重点检测。本文依托实体工程,在典型路段内采用无损检测等多种手段对旧路路基路面进行详细检测,分析得到旧路破坏原因及层位,并根据全线检测结果和典型路段的检测结果,对旧路进行了划分,并给出相应的处置建议。实践证明该方法可靠,达到了预期目标。
The old road renovation and expansion project, the old road testing and assessment of the project design and research work. The general test method is to use a variety of means to detect the entire line, but this test method is not obvious, you need to spend more manpower and material resources. Therefore, this paper presents a typical road segment detection method, on the basis of several full-line detection of the road surface, the more typical disease sections are selected and tested by a variety of means. This article relies on the physical engineering, using a variety of means such as non-destructive testing in a typical section of the road subgrade to conduct a detailed examination of the old road to analyze the causes and layers of damage, and based on the full range of test results and typical sections of the test results, Were divided, and given the appropriate disposal recommendations. Practice has proved that the method is reliable and achieves the expected goal.
