###### Abstract  
A depth precast deck panel (FDDP) is one element of the prefabricated bridge element and systems (PBES) that allows for quick un-shored assembly of the bridge deck on-site as part of the accelerated bridge construction (ABC) technology. This paper investigates the structural response of full-depth precast deck panels (FDDPs) constructed with new construction materials and connection details. FDDP is cast with normal strength concrete (NSC) and reinforced with high modulus (HM) glass fiber reinforced polymer (GFRP) ribbed bars. The panel-to-girder V-shape connections use the shear pockets to accommodate the clustering of the shear connectors. A novel transverse connection between panels has been developed, featuring three distinct female-to-female joint configurations, each with 175-mm projected GFRP bars extending from the FDDP into the closure strip, complemented by a female vertical shear key and filled with cementitious materials. The ultra-high performance fiber reinforced concrete (UHPFRC) was selectively used to joint-fill the 200-mm transverse joint between adjacent precast panels and the shear pockets connecting the panels to the supporting girders to ensure full shear interaction. Two actual-size FDDP specimens for each type of the three developed joints were erected to perform fatigue tests under the footprint of the Canadian Highway Bridge Design Code (CHBDC) truck wheel loading. The FDDP had a 200-mm thickness, 2500-mm width, and 2400-mm length in traffic direction; the rest was over braced steel twin girders. Two types of fatigue test were performed: incremental variable amplitude fatigue (VAF) loading and constant amplitude fatigue (CAF) loading, followed by monotonically loading the slab ultimate-to-collapse. It was observed that fatigue test results showed that the ultimate capacity of the slab under VAF loading or after 4 million cycles of CAF exceeded the factored design wheel load specified in the CHBDC. Also, the punching shear failure mode was dominant in all the tested FDDP specimens. fatigue loading; precast full-depth deck panel; joint fill materials; GFRP bars; UHPFRC

stress concentrations in the panels [3]. The transverse panel-to-panel connection has shear keys to protect adjacent panels from relative vertical movement due to traffic load. The panel-to-panel connection has several shapes, including the male-female shear key. However, cracking, spalling, and leakage were observed in such joints. Other panel-to-panel connections included a female-to-female shear key, which comes in bulb and diamond shapes [4; 5; 6; 7]. The incorporation of longitudinal reinforcement was achieved using overlapping U-bars and HS spirals, or employing open or closed steel tubes [8; 9]. Grouting materials have to be used to fill the shear pockets and transverse joints [10]. UHPFRC, as the filling material of the closure strip between connected FDDPs, has numerous benefits, including reduction of joint size, improved durability, speed of construction, and prolonged usage life [11; 12; 13; 14; 15]. GFRP reinforcement is a composite material made of polymer matrix reinforced with fibers. It has a high strength-to-weight ratio, is corrosion-free, and lasts longer [16]. A GFRP bar has relatively weak interlaminar shear strength governed by the weak matrix. The bond force in the GFRP bar is transferred to concrete by friction, adhesion, and mechanical interlock, provided that adequate concrete cover is available. GFRP bars as an internal reinforcement are a practical choice for replacing deteriorated concrete bridge deck slabs owing to reinforcing steel bar corrosion [17; 18; 19; 20; 21].
