摘要
在微表处施工中,良好的矿料级配是沥青混合料性能的重要保证,对各个国家选用的微表处矿料级配范围进行研究分析,并对各个国家对微表处用集料砂当量及其它质量要求进行了分析比较,提出了相关建议。
Good stone materials gradation is important to the performance of asphalt mix ture. Stone materials gradation limits about micro-surfacing in different countries and analyze aggregate sand content ＆ stone materials quality requirement were studied. The related suggestions were put forward on the basis of the study and analysis.
