水泥混凝土路面损坏评价方法

Distress Condition Evaluation for Concrete Pavements

本文根据水泥混凝土路面损坏的特征和起因,对于损坏类型和严重程度的分类和分级,给予了明确的定义和规定。采用路面状况指数PCI作为路面损坏的评价指标。通过主客观相结合的方法,提出了PCI的评定关系式。最后,探讨了如何依据损坏状况确定路面养护和改建的类型和措施。

In this paper, the definitions: severity levels and measure ment methods are developed for identifying distresses of concrete pavements, as the results of many previous studies on the cause and characteristics of pavement distress. A pavement condition index PCI is adopted for evaluating the pavement distress condition which is formulated by pavement condition survey and condition rating test. Finally, the problem whether the pavement should be repaired through maintenance work or through reconstruction is discussed.
