Experimental and Numerical Studies on FRC for Use in Dowel-Jointed Rigid Pavements
High initial investment acts as a deterrent in the large-scale adoption of rigid pavements in India. Usage of fibre-reinforced concrete, FRC, can help improve the performance characteristics of rigid pavements, thereby leading to reduced sections, bringing down the cost of construction. In this paper, a comparison study between the strength and durability parameters of FRC specimens when steel, glass, polypropylene, nylon, polyester and coir fibres are added at specified percentages was conducted. The optimum dosage for each fibre was obtained. The maximum load carried as well as the corresponding deflection at the dowel joint, for the various FRC pavement specimens made of optimum fibre dosage, was then obtained. A numerical nonlinear static analysis was then conducted using the finite element software ANSYS, and the experimental results were validated. Results show that with the addition of fibre there is an increase in the compressive, flexural and split tensile strength as well as an improvement in impact resistance, abrasion resistance and resistance to crack formation. Synthetic fibres can be seen to give good economical results, whereas a natural fibre like coir can be used to a reasonably good extent if available in abundance.
