随着宁夏农村公路的不断实施,水泥混凝土路面结构被广泛应用,但由于设计,施工等方面存在着一定缺陷,再加上路面经受重交通荷载、外部环境条件等作用,致使水泥混凝土路面使用性能下降,引起路面的断板,影响了公路投资使用效益和行车安全,因此,必须采取措施,加强对水泥混凝土路面的设计、施工及养护管理,减少断板率,积极采取措施加以防治,提高路面使用寿命周期。
With the continuous implementation of rural roads in Ningxia, cement concrete pavement structure is widely used, but due to the design, construction and other aspects of the existence of certain shortcomings, coupled with the road to withstand heavy traffic loads, external environmental conditions and other effects, resulting in the performance of cement concrete pavement Therefore, it is necessary to take measures to strengthen the design, construction and maintenance of cement concrete pavement, reduce the rate of broken plate, take active measures to prevent and control and improve the pavement Life cycle.
