| 摘 要： | 空隙率是影响路面使用性能的一个重要指标,它的变化直接影响道路使用性能,而空隙率又受密度测定方法影响。文章采用不同密度测定方法,对废旧橡胶颗粒沥青混合料密度进行检测,并分别计算其空隙率。通过与普通沥青混合料作对比,得出掺入橡胶颗粒后沥青混合料空隙率的变化规律,并对不同密度测定方法下得出的空隙率进行比较分析,得出密度测定方法对空隙率影响的变化规律。

| Abstract: | Voidage is an important index to influence pavement performance.Its change can affect highway use performance directly,and it is affected by density measurement method.This paper uses different density measurement methods to measure density of Waste rubber particles asphalt mixture and calculate its voidage.Compared with common asphalt mixture,change rule of voids in asphalt mixture incorporated of rubber particles is obtained,and through comparative analysis of voidage got in different density measurement methods,the change rule of the effect of density measurement methods on voidage is concluded. |
