Abstract

Due to increase in bitumen prices in the last few years in the country and romotion of the usage of concrete pavements, particularly the usage of Roller Compacted Concrete RCC in urban and suburban roads construction the application of combined pavement has been developed. Also the usage of asphalt overlay to create a suitable surface for deriving on the concrete surface is suggested. The methodology proposed in this study is using metal Fibers and polymer Fibers, separately, to strengthen the RCC. To increase the bending, tensile and compressive strength of concrete to reduce cracking and failure of the concrete RCC could be a preventive agent. For this study, first, roller concrete mix design was developed and was built as an indicator of tensile strength and compressive and flexural tests were performed on it. The obtained results were recorded as index Results. The following two types of metal Fibers with consumption 0. 5% and 1% in unit volume and polymer Fibers with the use of 0. 3 and 0. 6% in unit volume in the plans mixture was used this Fiber to mix design base were added. Fibers made from blends of standard cylindrical samples with dimensions of 30 x 15 and 50 x 15 x 15 cm prismatic beam samples were made and after processing all the sample tests to determine the compressive strength, flexural and tensile were. The 28 days results indicate that the metal Fibers to the RCC at a rate of 0. 5% and 1% respectively per unit volume increases the compressive strength of concrete roller 10. 1% and 13. 9% respectively and increases the tensile strength 29. 5% and 45% and increased bending strength up to the 40. 6% and 66. 5%. And with the addition of polymer Fibers at a rate of 0. 3% and 0. 6% per unit volume increases the compressive strength of RCC by 5. 06% and 6. 32% and increase the tensile strength of the order of 21. 1% and 31% and increased the bending strength of the 29. 1% and 42. 7% lead.
