EXPERIMENTAL STUDY ON COMPRESSIVE RESILIENT MODULUS OF POLYPROPYLENE FIBER REINFORCED CEMENT STABILIZED MACADAM
-
摘要: 根据大量试验结果,分析了试件养护龄期、聚丙烯纤维体积掺量以及水泥掺量对聚丙烯纤维水泥稳定碎石抗压回弹模量的影响,得出了相应的影响规律.结果表明:聚丙烯纤维的掺加对水泥稳定碎石抗压回弹模量有明显的降低;随着试验龄期的增长,抗压回弹模量不断增大;在聚丙烯纤维体积掺量小于1的范围内,随着纤维体积掺量的增加,水泥稳定碎石抗压回弹模量有逐渐减小的趋势;随着水泥掺量的增加,聚丙烯纤维水泥稳定碎石抗压回弹模量基本呈线性增长.Abstract: Based on plenty of experiment results,the effect of curing period of specimens,volume content of polypropylene fiber and cement content on compressive resilient modulus of cement stabilized macadam is analyzed,and the corresponding influencing rules are drawn. The study results indicate that the addition of polypropylene fiber can decrease the compressive resilient modulus of cement stabilized macadam evidently. The compressive resilient modulus is increasing with the increase of curing period. Within the range of the fiber content in this study (the volume content 1),there is a tendency of decrease in compressive resilient modulus with the increase of polypropylene fiber volume content. With the increase of cement content,the compressive resilient modulus of cement stabilized macadam is increasing linearly.
