عنوان مقاله [English]
Roller-compacted concrete (RCCP) is a zero-slump and stiff-dry mixture which is usually placed with an asphalt paver and compacted by conventional vibratory roller compactors to achieve the required density. Typically, the RCCP is constructed without joint. It needs neither forms nor surface finishing, nor does it contain bar reinforcing and dowels. Consequently, considering a proper mix design, load transfer can be achieved through aggregate interlock. Nevertheless, RCCP can be reinforced with fibers in order to improve the durability, flexural strength, load transfer capacity, and so on. Accordingly, this research was conducted to study the effects of fibers on the mechanical properties of RCCP and present a prediction fatigue model based on third-point beam fatigue test. Based on three-point bending test results on notched beam, fiber, cement, and water linearly affect the flexural strength. However, fiber tended to influence the fracture energy more significantly than flexural strength. It was found that stress ratio, fiber content and fracture energy was the significant term to predict fatigue life, respectively.
