Experimental Investigation on the use of Fiber Reinforced Concrete in Rigid Pavement

The project is a research experiment into the application of fiber reinforced concrete (FRC) to improve the performance of rigid pavement systems. Rigid pavements, made up normally of plain cement concrete, are susceptible to cracking and wear under heavy loading and exposure to the environment. To overcome such limitations, the use of discrete fibers like basalt, polypropylene, or glass fibers in concrete mixtures is examined. Fibers are likely to enhance mechanical characteristics like tensile strength, impact resistance, and postcracking behavior. The experimental program emphasized the full-scale testing of slabs through a Universal Testing Machine (UTM), mimicking realistic load conditions comparable to those faced by real pavement systems. The slabs were cast and cured in controlled environments, followed by concentrated loading to evaluate load-carrying capacity.Flexural strength, compressive strength, and elastic modulus test is also conducted using appropriate specimens. The study points to the potential of fiber reinforced concrete as a good material for rigid pavement use, with the promise of longer service life and lower maintenance requirements. The research also offers suggestions for the best fiber types and dosages for use in the field in road infrastructure.
