Research Progress on Mechanical Properties of Polymer Synthetic Fiber Reinforced Cement Stabilized Macadam
摘要
Abstract
To promote the application and development of polymer synthetic fiber-reinforced cement stabilized macadam(CSM)in pavement bases,the mechanical strength enhancement mechanisms of CSM and fiber-reinforced CSM are systematically analyzed,and the appropriate fiber lengths and dosages for different fibers in CSM are determined.The results indicate that,in terms of suitable fiber length,polyethylene terephthalate(PET)fiber length ranges from 50 mm to 70 mm,polypropylene(PP)fiber length ranges from 18 mm to 20 mm,and polyvinyl alcohol(PVA)fiber length ranges from 12 mm to 24 mm.Regarding the optimal fiber dosage,PET fiber content is 0.06%～0.08%,PP fiber content is 0.05%～0.15%,and PVA fiber content is 0.03%～0.09%.Under the appropriate length and dosage,the mechanical strength of CSM reinforced with PET fibers was enhanced by 7.0%～37.5%,that with PP fibers by 2.4%～161.1%,and that with PVA fibers by 3.4%～52.0%.PVA fiber can increase the compressive resilient modulus(RM)of CSM,while PET and PP fibers reduce RM.Polymer fibers show potential in improving the mechanical strength of CSM and merit further investigation.关键词
