摘要
分析了目前常用的SGC旋转压实原理.研究了不同旋转次数下微表处混合料体积指标的变化。对于微表处混合料,Ndesign、Nmax分别给出了建议取值。分析了不同油石比下微表处混合料的体积指标.并推荐了采用Superpave体积设计方法评价微表处混合料性能时混合料应满足的要求。
This paper introduced the principle of gyratory compaction, studied the volume index variation of micro-surfacing mixture at different compacting times, determined the proper value for Ndesign, and Nmax, recommended the index requirement in Superpave volume design method for micro-surfacing mixture.
