摘要
在大量试验研究的基础上,对试件养护龄期、聚丙烯纤维体积掺量以及水泥掺量的变化对聚丙烯纤维水泥稳定碎石抗压强度的影响进行分析。结果表明:聚丙烯纤维的掺加对水泥稳定碎石抗压强度有一定的增加;随着试验龄期的增长,抗压强度不断增长;在聚丙烯纤维掺量体积分数小于1‰的范围内,随着纤维体积分数的增加,水泥稳定碎石抗压强度和抗拉强度均有增加的趋势;随着水泥掺量的增加,聚丙烯纤维水泥稳定碎石抗压强度基本呈线性增加。
Based on plenty of experimental studies, the effect of curing period of specimens, volume content of polypropylene fiber and cement content on compressive strength of cement stabilized macadam is analyzed. The study results indicate that the addition of polypropylene fiber has certain reinforcement to the compressive strength of cement stabilized macadam. The compressive strength is increasing with the increase of curing period. Within the range of the fiber content that is less than 1‰ in this study, there is a tendency of increase in compressive strength and tensile strength with the increase of polypropylene fiber volume content. With the increase of cement content, the compressive strength of cement stabilized macadam is increasing in linearity.
