FIBER-REINFORCED RECYCLED CRUSHED CONCRETE AS A STABILIZED BASE COURSE FOR HIGHWAY PAVEMENTS

摘要: An experimental investigation consisting of unconfined compression tests, split tensile and beam flexure tests has been performed on a stabilized, fiber-reinforced, recycled crushed concrete aggregate to evaluate its potential usefulness as base course in highway pavements. Results show that, when is stabilized with little 4% cement fly ash by dry weight the mix, it can develop adequate strength serve high quality material. Furthermore, incorporation an appropriate proportion suitable fiber, this lean mix achieves spit flexural strengths which are about one-half corresponding regular concrete. The toughness or energy absorption fiber-reinforced specimens increased much 30 times compared absorbed unreinforced specimens. Hence, composite material, consists primarily waste materials, offers considerable promise for use construction rehabilitation
