The paper investigated the use of fiberglass-reinforced plastic (FRP) grid for reinforcement in link slabs for jointless bridge decks.\r\nThe design concept of link slab was examined based on the ductility of the fiberglass-reinforced plastic grid to accommodate bridge\r\ndeck deformations. The implementation of hybrid simulation assisted in combining the experimental results and the theoretical\r\nwork. The numerical analyses and the experimental work investigated the behavior of the link slab and confirmed its feasibility.\r\nThe results indicated that the technique would allow simultaneous achievement of structural need, lower flexural stiffness of the\r\nlink slab approaching the behavior of a hinge, and sustainability need of the link slab. The outcome of the study supports the\r\ncontention that jointless concrete bridge decks may be designed and constructed with fiberglass-reinforced plastic grid link slabs.\r\nThis concept would also provide a solution to a number of deterioration problems associated with bridge deck joints and can be\r\nused during new construction of bridge decks. The federal highway administration provided funds to Louisiana Department of\r\nTransportation through the innovative bridge research and development program to implement the use of FRP grid as link slab.
