摘　　要：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 wear test of micro-surfacing is the main technical indicator to evaluate water damage resistance performance of micro-surfacing mixture. Based on the grey relation analysis, this paper analyzes the correlation degree between wet-wheel wear value and the sand equivalent, methylene blue value, specific surface area SA and filler-asphalt ratio in different asphalt content of micro-surfacing mixture. The results show that under the lower asphalt-aggregate ratio the principal factors influencing the water stability of Micro-surfacing are methylene blue value and specific surface area, and under higher asphalt-aggregate ratio, the principal factor is composite material specific surface area.
