水泥稳定碎石是路面结构的主要承重层,以其水稳性好、承载力高、刚度大且较经济的特点,已广泛应用于高速公路和城市道路中,但是水泥稳定碎石随着时间的变化,该非均质体系发生变化,混合料的宏观物理性能如强度、抗收缩性和抗疲劳性均发生变化,并会带来一些路面病害,最常见的是路面裂缝,因此如何提高抗裂性能,减少水泥用量,成为水泥稳定碎石施工的焦点。常规的重型击 Cement stabilized macadam is the main load-bearing layer of pavement structure. It has been widely used in expressways and urban roads due to its good water-stability, high bearing capacity, high rigidity and economy. However, Changes in the heterogeneous system, the macroscopic physical properties such as strength, shrinkage resistance and fatigue resistance of the mixture change and cause some road disease, most commonly pavement cracks, so how to improve resistance Cracking performance, reduce the amount of cement, become the focus of construction of cement stabilized gravel. Regular heavy blow
