Abstract: 
Since 2007, the Korea Institute of Construction Technology (KICT) implemented the SUPER Bridge 200 project intending to develop UHPC materials as well as technologies for its application to bridges. This paper evaluates the field applicability of UHPC through the trial construction of a bridge executed in the last stage of the project. Even if the trial bridge is featured by a span length of 11 m and width of 5 m, its construction necessitates all the technologies required for the construction of a UHPC bridge. The cross-section was designed so as to secure the constructability and to maximize the efficiency of UHPC material. This resulted in a superstructure with a weight reaching merely one third of conventional slab bridges. Owing to an efficient design and the know-how gathered in the fabrication of UHPC, the fabrication and erection processes of the UHPC girder were carried out easily. Consequently, it can be stated that the UHPC bridge technology developed in this research has matured to a level enabling its immediate application on field.
