Full span form panel bridges are bridges constructed of prestressed precast panels spanning from pier to pier and covered with a composite topping concrete. This research concerns such full span bridges. Research consists of field investigations, including corings, analytical modeling, laboratory testing, and field testing. Results demonstrate safety of bridges designed using A.A.S.H.T.O. effective width formula and describe details thought to be capable of reducing cracking observed in existing full span form panel bridges.
