Abstract: This study investigates the structural performance of Glass Fibre Reinforced Polymer (GFRP) bridge deck panels fabricated using the hand lay-up method. Three different GFRP configurations—Chopped Strand Mat (CSM) with isophthalic resin, Woven Roving (WR) with isophthalic resin, and WR with epoxy resin—were analyzed. A total of six 1:3 scaled bridge deck models were fabricated and tested under static flexural, shear, and fatigue loading conditions. The results demonstrate that all configurations exhibited linear elastic behavior with brittle failure modes, and WR + epoxy resin panels outperformed others in fatigue resistance. Finite element analysis using ANSYS and ABAQUS was conducted to validate the experimental results and perform parametric optimization under IRC Class A loading. The study confirms the suitability of low-cost, hand lay-up GFRP bridge deck panels for use in modular and temporary bridges, and it provides essential design data to support future implementations in bridge infrastructure
