水泥混凝土路面属刚性路面,具有承载能力大,稳定性好,使用寿命长,日常养护费用少等优点,而且施工方便,程序简单,所以广泛运用于各等级公路。但水泥混凝土路面对路面基层的要求比较高(如反射裂缝对路面的影响比较大),因此积极开发基层筑路材料,研究与控制路面基层材料的选用和施工,改进路基性能,对提高公路质量具有重要意义。
Cement concrete pavement is a rigid pavement with advantages of large carrying capacity, good stability, long service life and low daily maintenance costs. It is also convenient for construction and simple in procedure, so it is widely used in all grades of highways. However, the requirements of cement concrete pavement on the grassroots level is relatively high (such as the impact of reflective cracks on the pavement is relatively large), so actively develop grassroots road construction materials, research and control of pavement grassroots materials selection and construction, improvement of roadbed performance, Quality is of great importance.
