UHPC Connection of Precast Bridge Deck

---

Abstract

Ultra high performance concrete is very promising material for many construction applications. Its outstanding features are generally known [1][2]. UHPC should be used in complex structural details like joints of precast elements. 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 and connections was experimentally verified using three different experiments. The performance of beams with precast slab with UHPC joint and cast in situ slab was compared.
