| 摘 要： | 通过对大粒径沥青混合料 (LSAM)的结构特性、室内路用性能试验及试验路车辙实测结果分析 ,首次提出结构特性参数骨架接触度SSC和骨架稳定度S的概念 ,在此基础上 ,将LSAM的组成结构定量的划分为三种结构 :紧排骨架 -密实结构、松排骨架 -密实结构及悬浮 -密实结构。其中 ,松排骨架 -密实结构的LSAM综合使用性能最好、应用范围更广、适用性更强 ,因而具有较好的经济和社会效益 |
| 关 键 词： | LSAM 路用性能 骨架接触度 骨架稳定度 沥青混合料 |

| Abstract: | By analysis on characteristic of structure,test on performance of pavement and measure of track on test road,parameter of structural characteristic,ie.Two concepts of contacting degree of skeleton SSC and stability of skeleton S of the large stone asphalt mix(LSAM)are put forward firstly.Thereby the LSAM can be divided into three kinds of structure:close skeleton compact structure,loose skeleton compact structure and suspension grain compact structure.For the service properties,applied area and applicability,loose skeleton compact structure therein is the best,thus there are good benefit to economy and society. |
| Keywords: | LSAM pavement performance contacting degree of skeleton stability of skeleton asphalt mixture |
