摘要
重载交通情况下,特别是路口、急转弯道等路段,沥青路面受车辆荷载、水、油等各种不利因素综合作用,往往达不到预期的使用年限。本文以福建省罗源县某公路路面改造工程为例,对沥青路面损坏情况展开调查,得出重载作用下沥青路面早期典型病害:以水损破坏为主引起的面层松散、剥落、坑槽以及车辆水平剪应力作用下形成的推移、拥包等。本文结合该公路交通荷载特点、破坏路段位置、路面结构等因素对病害原因进行分析,给出一系列防治措施,以供后续工程参考。
Asphah pavement eft＇coted by various unfavorable factors just as vehicle loading, water and oil when used. Asphalt pavement u- sually can＇ t reach its expected life when in heavy vehicle loading, especially in intel^eetion, sharp curve roads. In this paper, we take a certain pavement reconstruction project as an example in Luoyuan Fujian to research by. The early typical diseases of asphalt pavement un- der heavy vehicle loading are loose, flaking, pits main caused by water and slippage, swelling caused by horizontal stress from vehicles. We analyzed the causes of the disease and given a series of preventive measures in connection with the road traffic load characteristics, the location of damage, road constnwtion and other factors.
