AbstractUsing ultra high performance fibre reinforced concrete (UHPFRC) can lead to the construction of structurally-efficient bridge superstructures that will require fewer girder lines and minimum maintenance resulting lower life cycle costs than conventional cycle performance. UHPFRC could enable major improvements over conventional or ordinary concrete (OC) bridges in terms of structural efficiency, durability and cost-effectiveness over the long term. A simplified design approach of concrete slab on UHPFRC girders bridge using the Canadian Highway Bridge Design Code is proposed. The use of UHPFRC results in a more efficient design of the superstructure through a significant reduction in number and size of girders and then weight of the superstructure. This reduction leads to significant reduction in the dead load on the substructure, which is very beneficial especially for the case of aging bridges.
