路面水泥混凝土盐冻参数与评价指标研究

Research on the deicer-frost parameters and evaluation index of cement concrete pavement

针对目前盐冻试验标准在试件成型、测试与评价方法上存在较大差异的问题,对比研究了盐冻试验参数以及评价方法对路面混凝土的适应性,建立了路面混凝土盐冻的试验参数以及评价方法,并结合国内外混凝土盐冻破坏评价指标,提出了路面混凝土评价指标的建议值。

According to the present salt scaling test standard,there was a big difference problem in the specimen molding,test and evaluation method.Compared with the salt scaling test parameters and evaluation method to the adaptability of the concrete pavement, the pavement concrete test parameters and evaluation method was set up, and combined with concrete salt scaling damage evaluation index at home and abroad, the recommended value of the concrete pavement evaluation index was put forward.
