In line with the theories of the present pavement designs , the cement concrete pavement , with normal performance in the structure of every layer , ideal interlayer contact as well as good designs and construction , will usually not break until a long time of use or the time designed 按照現(xiàn)行路面設(shè)計理論,路面結(jié)構(gòu)各層性能正常、層間界面接觸理想、設(shè)計和施工質(zhì)量良好的水泥混凝土路面,一般要經(jīng)過長期使用且達(dá)到其設(shè)計使用年限后才會開裂破壞。
