为探讨间断级配对微表处性能的影响,通过湿轮磨耗、轮辙变形试验对比研究欧盟(EU)、俄亥俄州(OH)2种间断级配微表处路用性能与纤维掺量、油石比的关系；通过构造深度、渗水试验对比分析MS-3型连续级配与EU、OH间断级配微表处抗滑性能、防水性能的差异.结果表明：相同条件下,EU型微表处的抗车辙性能优于OH型,而耐磨耗性、抗水损害性能恰好相反；与连续级配相比,间断级配微表处路用性能同样满足规范要求,且EU型抗滑性能相对较优,OH型封水效果更好；间断级配纤维微表处路用性能优劣取决于纤维掺量及油石比,二者分别为0.10%~0.25%、7.0%~8.0%时路用性能最佳.

In order to study the effect of gap-graded to micro-surfacing performance, the relations of fiber content, asphalt-aggregate ratio with pavement performance of micro-surfacing were comparatively investigated under the conditions of European Union and Ohio gap-graded by wet wheel abrasion test and rut deformation test in this paper. Then texture depth test and seepage test were conducted for comparative analyzing the difference of skid resistance, water resistance performance of micro-surfacing in different gradations, which includes MS-3, EU and OH type gradations. The results show that rutting resistance of EU gap-graded fiber micro-surfacing is better than that of OH, but abrasion performance and water damage performance are opposite under the same conditions. The pavement performance of gap-graded micro-surfacing also satisfy regulatory requirements by comparing with continuous gradation. And anti-slide performance of EU is relatively better, while water sealing effect of OH is better. The pavement performance merits of gap-graded fiber micro-surfacing depends on fiber content and asphalt-aggregate ratio, which is the best after adding 0. 10% to 0. 25% fiber and 7. 0% to 8. 0% asphalt-aggregate ratios respectively.
