用于微表处的集料性能研究

Research on Aggregate Performance of Micro- Surfacing

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高低温性能、耐磨性能，抗车辙能力等性能改善较显著；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。为同类工程提供参考。

The paper analyses the aggregate at different levels and the effect of different sand-table equivalent on the micro-surfacing mixture proformance by laboratory test. The results shows that reasonable aggregate mixture would improve the performance of mixture in high and low temperature, wear-resistance and anti-rutting ability a lot. The more aggregate sand equivalent involves, the better micro-surfacing mixture of anti-wear and anti-round ability become. The research could provide valuable reference for similar projects.
