Application of UHPC Joints in Precast Structures

Acceleration of bridge construction requires the development of new construction methods. In composite steel concrete bridges the cast in situ bridge deck may be replaced by a precast deck. For fast assembly the joints have to be solved adequately. UHPC joints represent an alternative which can satisfy the requirements on mechanical properties of joints, on construction and economy. The function of the joints was experimentally verified using three different experiments. The performance of beams with precast and cast in situ slab was compared.
