This paper is the report where PCa concrete panels are applied to existing PC composite girders for concrete slab replacement project. It is the common way that the concrete slabs are casted on the concrete girders for slab replacement, but in this project the precast panels are used for the rapid construction. The detail of design is repotred from structural aspect, especially the connection between girders and panels, fatigue strength.
