随着交通负荷的增大,在重交通荷载、超载、水毁、其它自然环境等诸多外部因素的影响下,水泥混凝土路面行车后不久就出现了许多不同程度的病害,导致路面的使用性能迅速下降,严重地影响了车辆快速、安全行驶,而且给养护和维修带来了巨大的压力。水泥混凝土路面的水毁现象也不比较严重,路面受水的侵蚀,在综合因素及环境、气候等影响下基层失稳,产生病害。通过分析水毁原因,从设计、施工、养护三个环节提出防治办法。
With the increase of traffic load, under the influence of many external factors, such as heavy traffic load, overload, water damage and other natural environments, the cement concrete pavement has many different degrees of shortly after driving, which leads to the rapid performance of pavement Decline, seriously affecting the vehicle quickly and safely driving, but also to the maintenance and repair has brought tremendous pressure. Cement concrete pavement water damage is not serious, the road by water erosion, under the combined factors and the environment, climate and other grass-roots instability, resulting in disease. By analyzing the causes of water damage, we put forward the measures for prevention and control from the three aspects of design, construction and maintenance.
