近几年,随着公路基础建设的加大,水泥混凝土路面(白色路面)具有刚度大、承载能力强、稳定性好的等优点被得到广泛实施,但由于设计、施工和养护管理存在一定缺陷,致使水泥混凝土路面使用性能下降,引起路面的断板,影响了公路运输的效益和行车安全,因此,必须采取相应措施,防止断板,提高路面的使用性能。
In recent years, with the increase of highway infrastructure, cement concrete pavement (white pavement) has been widely implemented due to its advantages of high rigidity, strong carrying capacity and good stability. However, due to the defects of design, construction and maintenance management , Resulting in decreased performance of cement concrete pavement, causing the broken road pavement, affecting the efficiency of road transport and traffic safety, therefore, must take appropriate measures to prevent broken plate, improve the performance of the road.
