摘要
采用填料体积等效置换方法对化学类抑制冻结沥青混合料进行配合比设计,通过马歇尔试验方法检验盐化物添加量对马歇尔试件体积指标、油石比及混合料路用性能的影响。试验结果表明,在相同矿料级配条件下,盐化物添加量对沥青混合料马歇尔试件体积指标及油石比影响不大;通过控制盐化物添加量,盐化物沥青混合料路用性能能够满足规范要求。
By using filler equivalent volume replacement method to design the mixture proportion of chemical antifreezing asphalt mixture, the influences of salt addition in quantity on Mashall volume parameters,asphalt-aggregate ratio and road performance are tested. The results show that the influences of salt addition in quantity on Mashall volume parameters is not obvious when the aggregate grading is identical. By controlling the salt addition in quantity, the road performance of chemical antifreezing asphalt mixture is able to meet the demand of the code.
