水泥混凝土路面既要承受高速载重车辆的重荷、冲击和磨损作用,又要承受自然因素特别是温差、干湿和冻融引起的破坏作用。因此要用适应道路工作条件的特种水泥,使混凝土能满足抗压和抗折 Cement concrete pavement should not only bear the heavy load, impact and wear of high-speed truck, but also bear the damaging effect caused by natural factors, especially temperature difference, wet-dry and freeze-thaw. Therefore, the use of special conditions to adapt to the road cement, so that concrete can meet the compressive and flexural
