Experimental study of the effects of micro and macro polymer fibers on the mechanical, physical and abrasion resistance of roller compacted concrete pavements

Roller-compacted concrete (RCC) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and without slump. It was shown that the application of fibers would enhance some properties of concrete, however in roller compacted concrete; there was a lack of knowledge. The application of RCC gained a great attention for physical, mechanical, durability and economical benefits. In this paper, the effects of synthetic polymeric fibers on the physical and mechanical of fiber roller compacted concrete pavement were experimentally investigated. To this means, three mixtures by using of micro and macro polymeric fibers made. The mechanical strength tests including compressive and flexural strength and also abrasion strength tests were carried out. The results showed that the application of synthetic polymeric fibers improves the mechanical (including the compressive strength, flexural strength) and physical properties (abrasion strength) of fiber reinforced roller compacted concrete (FRCC).
