路面直接承受交通荷载和车轮磨损,经常受到气候、水文等自然因素的影响,路面材料也会随着时间的推移而逐步老化衰变。倘若不及时进行养护维修,其使用性能就会逐渐降低,并很快影响到行车的安全、舒适和快速。有时微小的欠缺往往会发展成严重的破坏。可以肯定地说,无论哪一种路面都需要养护维修。路面养护无疑是公路养护部门尤其是道班的一项重要工作。一、路面养护维修的要求一般来说,路面养护维修就是在通常的交通和气候条件下,尽可能使路面保持平整、坚实、完好;路拱适度、排水通畅;行车顺适安全。同时有计划地对原有路面进行
Pavement directly bear the traffic load and wheel wear, often subject to climate, hydrology and other natural factors, pavement materials will gradually decay with aging. If not timely maintenance and repair, its performance will gradually reduce, and soon affect the safety, comfort and speed. Sometimes minor defects tend to develop into serious damage. To be sure, no matter what kind of pavement needs maintenance. Pavement maintenance is undoubtedly an important part of road maintenance departments, especially road classes. First, the maintenance requirements of the pavement maintenance In general, pavement maintenance and repair is under normal traffic and climatic conditions, as far as possible to keep the road surface formation, solid, intact; moderate road arch, drainage unobstructed; At the same time there are plans for the original road
