通过对水泥稳定级配碎石与水泥粉煤灰稳定级配碎石2种结构不同剂量结合料配合比的7d、28d、90d、180d等4个龄期抗压强度,90d龄期的抗弯拉与劈裂强度,以及施工延迟时间对强度的影响等室内试验结果的对比分析,结合2种结构试验路段的钻孔取芯强度等指标观测比较,表明水泥粉煤灰稳定级配碎石结构具有很多优点,具有显著的经济和社会效益。 Through four stages of compressive strength at 4d, 7d, 28d, 90d and 180d, the composites with two kinds of structures with different dosages of binder and binder of stabilized grade graded macadam and cement fly ash stabilized graded macadam, Tensile strength and splitting strength, as well as the impact of construction delay time on the strength of the indoor test results of comparative analysis, combined with two structural sections of the drill hole coring strength and other indicators comparison shows that the stability of cement fly ash graded stone structure Has many advantages, with significant economic and social benefits.
