水泥混凝土路面具有刚度大,强度高,稳定性好,耐久性好,初期养护费用少,有利于夜间行车等优点,是近几年高等级公路路面的两种主要形式之一。然而,由于水泥混凝土是一种弹性小,脆性大,收缩性强,抗变形能力差的非均质材料,在施工过程中,受现场施工条件,原材料,施工工艺与水平等因素的影响,水泥混凝土面板不可避免地会产生早期裂缝、开裂甚至断板。
Cement concrete pavement has the advantages of high rigidity, high strength, good stability, good durability, low initial maintenance cost and good nighttime driving. It is one of the two main forms of high-grade highway pavement in recent years. However, since cement concrete is a non-homogeneous material with small elasticity, high brittleness, strong shrinkage and poor deformation resistance, cement is affected by factors such as on-site construction conditions, raw materials, construction technology and level. Concrete panels inevitably produce early cracks, cracks and even broken board.
