文章在MTS-810上采用-10℃低温劈裂试验来比较在水泥替代矿粉的比例(质量比)分别为0%、20%、40%、60%、80%、100%的情况下,SAC25沥青混合料的低温抗裂性的变化情况。对实验结果采用不等重复试验的单因子方差分析检验不同水泥掺量对低温劈裂强度、破坏拉伸应变和低温破坏劲度的影响。得出水泥掺量对沥青混合料SAC-25低温性能无显著影响的结论。
In the article, the low temperature cleavage test at -10 ℃ was used to compare the results of the tests on the MTS-810 when the proportions (mass ratio) of cement instead of mineral powder were 0%, 20%, 40%, 60%, 80% and 100% SAC25 asphalt mixture at low temperature crack resistance changes. One-way ANOVA was used to test the effect of different cement content on the low-temperature splitting strength, failure strain and low-temperature damage stiffness. It is concluded that cement content has no significant effect on the low temperature performance of asphalt mixture SAC-25.
