Abstract

To address the shortage of the aggregate used in a hot mix asphalt (HMA) pavement in Guangxi, properties such as the aggregate crushing, polished stone, and Los Angeles abrasion values of a type of hard sandstone aggregate used in HMA were tested after various conditioning treatments. The hard sandstone aggregate met the technical requirements for aggregate in HMA. In addition, the influence of the Marshall compaction on the hard sandstone aggregate-combined grading was tested. The combined grading curve changed a little, and the aggregate satisfied the corresponding technical requirements. Therefore, according to the abovementioned results, the hard sandstone aggregate can be used as a coarse aggregate in HMA.

热拌沥青中硬砂岩骨料的测试与评估

为了解决广西热拌沥青（HMA）路面骨料短缺的问题，对 HMA 中使用的一种硬质砂岩骨料进行了各种养护处理后的骨料压碎值、磨光值和洛杉矶磨耗值等性能测试。硬砂岩骨料符合 HMA 中骨料的技术要求。此外，还测试了马歇尔压实对硬砂岩骨料组合级配的影响。综合级配曲线变化不大，骨料满足相应的技术要求。因此，根据上述结果，硬砂岩骨料可用作 HMA 中的粗骨料。
