摘要
通过对黄石地区既有水泥混凝土路面的广泛调研,对室内的水泥混凝土进行配合比设计(与现场检测混凝土配合比相同)并进行回弹值测定和抗压强度试验,运用最小二乘法对试验结果进行统计分析,得到黄石地区既有水泥混凝土路面的测强曲线。得到的测强曲线将有利于检测人员快速分析既有水泥混凝土路面强度,为大面积的旧水泥混凝土路面的治理改造提供理论支持。
Through extensive investigation to the existing cement concrete pavement in Huangshi region, mix proportion of indoor concrete was designed. The rebound method and compressive strength test were executed to concrete specimens and the least square method was applied to analyze test results. Then the strength curve of exiting cement concrete pavement in Huangshi region was obtained. The strength curve can help checking personnel to analyze quickly the strength of the existing cement concrete pavement, which is useful to provide theoretical support for rebuilding and improving the old cement concrete pavement in large scale.
