    14 Years of Service

    After 14 years of service the


    following observations are made:
    • No deck surface deterioration
    • No Corrosion of FRP materials
    • No Structural failures
    • No damage from debris
    (underside)
    Conclusion –
    FRP Materials are living up to the
    reputation!

    Prototyping and Testing
    • The testing program was broken
    up into five key tests:
    • Test 1: aggregate shear key tension Test 3: full scale U-girder and concrete
    test deck test
    • To test tensile capacity and Test ultimate moment capacity
    efflorescence of concrete
    Test ultimate shear capacity
    • Ultimate tensile capacity of shear
    key from direct tension (wave Test ultimate bending capacity of slab
    uplift) loads Test fatigue performance of slab over 2e6
    • Test 2: FRP reinforcing and concrete cycles
    deck capacity Test long-term creep performance
    • Test ultimate moment capacity Test longitudinal shear key capacity
    • Test ultimate shear capacity Test 4: FRP reinforcing bar tests
    • Test ultimate punching shear
    capacity Test tensile modulus
    • Test ultimate bending capacity of Test elastic modulus
    slab Test shear strength
    • Test fatigue performance of slab Test ultimate tensile strength
    over 2e6 cycles Deriving GFRP bond coefficient
    • Test long-term creep performance
    • Test longitudinal shear key capacity
    Test 5: U-Clip joint capacity
    Test shear and tension across U-clips in
