沥青路面破损原因检测与分析

路面出现破损后,需要对其进行检测与评估。通过调查,东环北路道路破坏形式主要为整个路段中间两车道均出现不同程度的龟裂和辙槽现象,局部已形成坑洞,且修补过的部位仍有龟裂现象。对路基回填土压实度、水泥稳定碎石基层、沥青混凝土面层厚度、压实度、油石比、面层弯沉等指标检测后,得出该路面过早的破损主要是由于上述指标没有完全达到设计所致的结论。

Testing and analysis of breakage on an asphalt pavement

Testing and evaluation of pavement will be acted when it appear breakage.Through investigation,we can find the main form of the East North Central road damage are whole sections of different degrees of cracking and rutting phenomenon, some of them have become the potholes, and the site repaired still had a cracking phenomenon.Compaction of the sub grade backfill,cement stabilized gravel,asphalt concrete surface layer thickness,compaction,bitumen/stone ratio, the surface layer were measured deflection test,we get premature damage of the road mainly due to the above indicators do not fully meet the design.
