按照常规分析 ,引发砼路面断板的原因主要有以下几个方面 :①温度裂缝 ;②路基不实产生不均匀沉降 ;③施工厚度不达标 ,重车辗压 ;④施工后养护工作不到位使强度降低等。但我公司在长期拆除大量砼路面断板时发现 ,即使许多砼路面的地基打得很实 ,厚度符合设计规定 ,施工也达标 According to the conventional analysis, the reasons for the initiation of concrete pavement breaking mainly include the following aspects: (1) temperature cracks; (2) subgrade subsidence caused by false foundation; (3) construction thickness is not up to the standard; Strength reduction and so on. But my company in the long-term demolition of a large number of concrete pavement found that, even though many of the concrete pavement foundation play very real, the thickness of the design requirements, construction standards
