中文摘要：

微表处是一种路面维修养护技术，对缓解路面病害的发生发展、延长路面使用寿命起到了积极作用。为提高微表处混合料的抗水损性及抗车辙性能，对微表处混合料路用性能影响因素进行研究。采用湿轮磨耗试验、负荷轮粘附砂试验和轮辙变形试验方法，通过使用不同级配、不同集料以及添加纤维，分析这些因素对微表处混合料的水稳定性以及抗车辙性等路用性能的影响。试验结果表明：玄武岩无论是在水稳定性能还是抗车辙性能都优于石灰岩；对于MS-Ⅲ型级配微表处混合料考虑水稳定性时，级配选定在上限与中值之间较好；微表处混合料以抗车辙性能为主时，级配选定在中值与下限之间较好；掺加2‰聚丙烯单丝纤维的微表处混合料可提高微表处混合料的抗车辙性能。

英文摘要：

Micro-surfacing is a kind of pavement maintenance technology and it plays a positive role for resisting distress and extending pavement service life. In order to improve moisture dam- age resistance and rutting resistance of micro-surfacing mixture, its road performance was stud- ied. The impacts of different gradations, aggregates and fibers on the water stability, rutting re- sistance and other road performances of micro-surfacing mixture were analyzed by using wet track abrasion test, load wheel test and stability and resistance to compaction test. The results show that basalt is better than limestone in terms of water stability and rutting resistance. For MS-m micro-surfacing mixture, gradation between upper limit and mid-value is better for moisture dam- age resistance, while the gradation between mid-value and lower limit is better in case of rutting resistance. Adding 2‰ polypropylene monofilament fiber can improve rutting resistance of micro- surfacing mixture. 7 tabs, 7 figs, 10 refs.
