Abstract

The purpose of this research is to evaluate the mechanical performance and durability of Roller Compacted Concrete (RCC) with fibers as an alternative to asphaltic pavements in industrial areas with heavy traffic loading. RCC is a hard and relatively dry mixture of aggregate (maximum nominal size 19 mm), cement and water which is spread by conventional asphalt pavement finishers and compacted by a vibrating roller. After completing the hydration reactions, the RCC has the same appearance as the concrete with zero slump. In this research the compressive and bending strength, durability and cycles of freezing and thawing were tested. The results showed that the performance of RCC containing fibers is better than RCC without fibers. Also, the resistance of RCC against fire is much higher than asphaltic mixture. The results showed that RCC pavement is suitable for roads with heavy vehicle traffic and low speed due to its engineering and mechanical characteristics. The main purpose of this research is to investigate the engineering and mechanical properties of RCC as an alternative to asphaltic pavement in industrial areas with heavy traffic loading. Also, by conducting a test, the fire resistance of RCC and asphaltic pavements was evaluated.
