摘要
采用新、旧规范提出的2种沥青混合料配合比设计方法对同一种沥青混合料进行配合比设计并进行路用性能检验。结果表明:采用新规范计算的沥青混合料的最大理论密度、空隙率、矿料间隙率和沥青饱和度以及确定的最佳油石比都比旧规范计算的要小,并且具有更好的高温稳定性和水稳定性,但抗渗性要差一些。
Two design methods of asphalt mixtures upon new-old technical specifications were used to design the same type asphalt mixtures respectively and their pavement performance was tested. The results showed that the theoretical maximum density,volume of air voids, voids in mineral aggregate and voids filled with asphalt, which were calculated by new technical specifications, was smaller than that were calculated with old technical specifications. And the former has better performance at high-temperature and capacity of moisture-resistance damage than latter but its impermeability was slightly worse.
