摘要
通过系统的试验,分析超细纤维的掺量对水泥稳定碎石抗压强度、劈裂强度、抗压回弹模量等路用性能指标的影响规律,试验结果表明:超细纤维的掺入可以有效提高水泥稳定碎石的强度,对抗压回弹模量影响不大,试验范围内,超细纤维水泥稳定碎石的抗压强度、劈裂强度随着超细纤维掺量的增大而提高。
Through systematic experiments,the influence law of superfine fiber content on the compressive strength,cleavage strength and compressive modulus of resilience were analyzed. The test results show that the addition of superfine fibers can effectively improve the strength of the cement stabilized macadam,and it will not affect the compressive modulus of resilience. The compressive strength and cleavage strength of superfine fiber cement stabilized macadam would increase with the superfine fiber content increase in the test range.
