| 摘 要： | 针对微表处技术的特点，通过室内试验分析了不同级配的集料及不同砂当量对微表处混合料性能的影响。结果表明，合理的集料级配对混合料的高低温性能、耐磨性能、抗车辙能力等改善效果显著；集料的砂当量越高，微表处混合料的抗湿轮磨耗和抗车辙能力越好。试验结果可为同类工程提供参考。

| Abstract: | Aimed at the characteristics of micro-surfacing technology,the influence of aggregate with different gradations and different sand equivalent on the performance of micro-surfacing mixture is analyzed.The results show that reasonable aggregate gradation can significantly improve the high-temperature and low-temperature performances,wear-resistance and anti-rutting abilities of mixture;when the sand equivalent of aggregate is higher, the anti-wear and anti-round abilities of mixture are better,which can provi... |
