路面不平整现象主要表现在坑凹、起拱、波浪、接缝台阶、碾压车辙、龟裂、桥头跳车等等。造成路面不平整的原因是多方面的,下面将逐一论述。路基不均匀沉降:路基是路面的基础。路基不均匀沉降必然会引起路面的不平整,路基不均匀沉降的主要原因有: 龉堤地基处理不当伐树根及表土处理不彻底,高路基形成后,一旦杂质腐烂将会造成路堤局面松软和不均匀沉降;地面横坡大于1∶5的路段,路堤填筑前土堪未按规
Uneven road surface mainly in the pits concave, arch, wave, seam steps, rolling ruts, cracking, bridge jumping and so on. There are many reasons for the uneven road surface, which will be discussed below. Uneven roadbed subsidence: Subgrade is the foundation of the road. Uneven embankment subsidence will inevitably lead to road roughness, subgrade uneven subsidence are the main reasons: improper treatment of embankment ground embankment roots and topsoil processing is not complete, the formation of high embankment, once the impurities will cause embankment decay loose and soft Uneven settlement; Landslide greater than 1: 5 road sections, embankment before filling soil can not withstand the rules
