规范在沥青混合料配合比设计方法中在计算理论最大相对密度过程中引进了矿料的有效相对密度,但对于高吸水率的玄武岩在沥青混合料配合比设计中体积指标的测算时的适用性问题是值得研究的。研究利用多孔玄武岩材料进行了沥青混合料马歇尔技术参数、路用性能的比对试验,探讨了多孔玄武岩混合料配合比设计中的体积参数获取的准确性和适用性问题。
The specification introduces the effective relative density of mineral aggregate in the calculation of theoretical maximum relative density in the mix design method of asphalt mixture. However, the applicability of the basalt with high water absorption in the calculation of the volume index in the mix design of asphalt mixture The problem is worth studying. The comparison of the Marshall technique parameters and the road performance of the asphalt mixture with the porous basalt material was studied. The accuracy and applicability of the volume parameter acquisition in the mixture ratio design of the porous basalt mixture were discussed.
