Abstract

The utilization of concrete pavements has been grown over the last decades because it has high durability and longer structural life compared with asphalt pavements. Cracks in concrete pavements present the main factor of pavement failure, and the major cause of appear cracks is the weak tensile and flexure properties of the concrete material itself. Therefore, utilizing discrete fiber in concrete is one option to decrease the weakness of concrete. This paper using the cylinder and beam specimens to understand the effect of two different types of discrete fibers and various volume on mechanical properties of concrete. Additionally, the excremental results were simulated by Finite Elements Method (FEM) through ANSYS software program. The mechanical properties for seven cases used in this study related to Fiber Reinforced Concrete (FRC) included compressive strength, modulus of elasticity, break strength, modulus of rupture, and flexural toughness. The outcome of the study indicated that low volume fraction of the steel and Polyvinyl Alcohol (PVA) fibers have little effect on the flexural capacity of concrete pavement, but steel fibers provide improvements that are more significant in toughness and residual strength than PVA fibers. Adding 0.4 and 0.6% steel fibers to concrete pavement provided flexural toughness up to 82 and 94 N.m, which is about 137 and 156 times, respectively. The analytical analysis by ANSYS software provided results which are close to experimental work with more safer design.
