| 摘 要： | 通过实测5种单一规格碎石堆积体的空隙率,总结出一定体积的不同单一规格碎石空隙率基本相同的规律;对单层单一规格碎石进行分析,找出碎石粒径的变化对封层时沥青用量和碎石用量的影响。又通过对施工时碎石产生的离析现象进行分析,进而找到减少或消除离析的方法。

| Abstract: | By measuring the void ratios of 5 types of accumulations comprising of one single size of gravels,a law was summarized,saying that for a certain volume,the void ratios of different gravels with the same size are basically the same;the analysis of single-layer gravels with one size was carried out to find out the influence of the changing of gravel size on amounts of asphalt and gravel during the sealing.The segregation of gravels was also analyzed,looking for a way to reduce it. |
