The present research project investigates lightweight and normal weight concrete precast panels for highway bridge decks. The deck panels are reinforced with Glass Fiber Reinforced Polymer (GFRP) bars. Due to the lack of research on lightweight concrete members reinforced with GFRP bars, the AASHTO LRFD Bridge Design Guide Specifications for GFRP Reinforced Concrete Decks do not permit the use of lightweight concrete when GFRP bars are used as flexural reinforcement. The ACI 440.1R-06 design guidelines do not provide any design information regarding the use of lightweight concrete reinforced with GFRP bars. In this research, the experimental performance of lightweight concrete versus normal weight concrete precast GFRP reinforced deck panels is investigated in terms of flexural capacity, panel deflections, and shear capacity.
