This paper presents the results of an experimental test series carried out to investigate the soil-structure-pavement interaction in the vicinity of the transition slab at the end of an integral bridge. The main function of transition slabs is to ease the transition between the bridge deck and the embankment in the case of differential settlement. Additionally, in the case of integral bridges, transition slabs can solve the problem of moderate imposed longitudinal deformations at the bridge ends. In this case the displacements imposed on the transition slab can lead to vertical and longitudinal surface displacements and to cracking of the pavement. Based on the observed behaviour, some recommendations are proposed for the geometry and surface conditions in order to optimize the behaviour of transition slabs.
