Abstract. The separated main connector of a prototype cassettes floating bridge, composed of a mandrel and an outer sleeve, is the subject of the experimental research presented in the work. Operating conditions, similar to those found in side connectors and in the roadway surface of a real joint prototype, are mapped during the lab tests. Determination of strain maps of the prototype joint sleeve walls is the purpose of these tests. Strength tests of the three-point bending of the separated bridge side connector were preceded by a preliminary strength analysis with the use of analytical models and FEM analysis. The range of loads used is selected in such a manner that the maximum stress occurring in the joint sleeve walls should not exceed the yield strength of the material. The electroresistance gauge method is supplemented with the optical image correlation methods for deformation measurements. With a continuous strain distribution maps are developed in this manner. The strain maps enabled a precise identification of the most stressed areas in the joint sleeve wall during the bending tests, as well as a strength assessment of the structural solution of the blind screw fixing mandrel in the connector sleeve.
