为了研究沥青混合料蓄盐式融雪阻冰型沥青混合料水稳定性,通过设计2种不同融雪盐的混合料,以浸水马歇尔试验和冻融劈裂试验分别测试不同种类混合料的水稳定性。研究发现2种蓄盐类混合料的浸水马歇尔残留稳定度相对于未掺加融雪盐的混合料变化不大;但冻融劈裂强度比下降较大,作为低温地区使用,仍待进一步研究。
In order to study the water stability of bituminous snowmelt and ice blocking asphalt mixture, the water stability of different kinds of mixture was tested by immersion Marshall test and freeze-thaw splitting test by designing the mixture of two kinds of snow melt salt. . The results show that Marsh residual stability of two kinds of salt mixture is less than that of unblended mixture. However, the ratio of freeze-thaw splitting strength decreases greatly. However, it is still to be further studied as low temperature region.
