基于同步薄层罩面技术(STC)施工工艺的特殊性,文章对STC沥青混合料和常规的AC、AK、SMA、Sup等沥青混合料进行了马歇尔试验,对比分析了各类型混合料的体积性能。对各类混合料进行了15℃劈裂实验,结果表明,罩面层厚度较薄时,STC间断级配混合料的性能更加优良。 Based on the particularity of STC construction technology, the Marshall test of STC asphalt mixture and conventional AC, AK, SMA, Sup asphalt mixture was carried out. The volume of each type of mixture was compared performance. The splitting experiments on various mixtures at 15 ℃ showed that the properties of STC discontinuous mixture were more excellent when the overlay thickness was thinner.
