道路工程质量问题分析
坑塘:路面表层局部松散,形成凹槽,在水浸和车辆作用下进一步扩大发发展为坑槽,严重影响着行车的安全性和舒适性。 面积破坏呈坑洼深度大于20mm,面积在0.04㎡以上。如小面积坑槽较多又相距0.2m以内,应合在一起丈量。

沉陷:路面、路基有竖向变形,路面下凹,深度30mm以上。

横向裂缝可分为荷载性裂缝和非荷载性裂缝两大类。

车辙是在行车荷载重复作用下,路面产生累计永久性的带状凹槽。

砼板角断裂:裂缝与纵横缝相交将板角切断,当其二个焦点距角隅均大于150mm,而边长一半并伴有沉陷或碎裂时,按板角断裂部分计算面积。

拱起:由于树根的生长造成的花岗岩拱起。多块板相对周围板向上突起,最大突起量在30mm以上。
