The purpose of this paper is to present fatigue and strength experimental qualifications performed for an all-composite bridge deck. The materials used for the fabrication of this 9.14 m (30 ft) long by 2.74 m (9 ft) wide deck were 76 mm (3 in) pultruded square hollow glass and carbon FRP tubes of varying lengths. These tubes were bonded using an epoxy adhesive and mechanically fastened together using screws in seven different layers to form the bridge deck with tubes running both longitudinal and transverse to the traffic direction. The cross-section of the deck was in the form of four identical I-beams running along the length of the bridge.
