The performance of rigid pavements is primarily determined by the type of reinforcement used. Steel, though strong and widely available, is prone to corrosion, which causes premature deterioration of reinforced concrete pavements in India. The corrosive nature of the environment leads to a loss of structural integrity, higher maintenance costs, and reduced service life. Glass Fiber Reinforced Polymer (GFRP) offers a non-corrosive alternative that provides higher tensile strength, lighter weight, and superior chemical resistance compared to steel. This study compares steel and glass fiber reinforcement in road construction. The Net Present Cost (NPC) of both materials is evaluated using the Life-Cycle Cost Analysis (LCCA) approach. Design and material guidelines from relevant standards and field data have been incorporated into the comparative framework. Under moderate and severe chloride exposure, the long-term cost of steel reinforcement increases sharply due to corrosion-related damage. Conversely, GFRP achieves lower life-cycle costs because of its superior durability, corrosion resistance, and ease of handling, despite its higher initial procurement cost. Factors such as maintenance accessibility, exposure severity, and workmanship quality play a crucial role in determining the most cost-effective reinforcement solution for rigid pavement design.
