微表处湿轮磨耗试验是评价微表处混合料抗水损害性能的主要技术指标,文中采用灰色关联分析法分析了不同油石比条件下微表处混合料的砂当量、亚甲蓝值、比表面积SA及粉胶比FB与微表处混合料湿轮磨耗值的相关联程度。结果表明,在较低油石比状况下对微表处湿轮磨耗试验中60min水稳定性影响最大的因素是合成矿料的比表面积SA与亚甲蓝值,在较高油石比时最大的影响因素是合成矿料的比表面积SA。
The wet wheel abrasion test of micro-surfacing is the main technical index to evaluate the water damage resistance of micro-surfacing admixture. In this paper, the gray relational analysis method is used to analyze the sand equivalent, methylene blue value, Specific surface area SA and the ratio of cement to binder FB and the wetting wheel wear value of the mixture at the micro-surfacing point. The results show that the most significant factor that affects the water stability of 60min at the wet-wheel wear test of micro-surfacing is the maximum effect of specific surface area (SA) and methylene blue value of synthetic mineral on the ratio of asbestos at lower surface area The factor is the specific surface area SA of the synthetic mineral.
