The work describes methodology of selection of a prototype articulated joint used to connect the segments of the concrete protection barrier. The barrier and the joint have been made according to the original project of the authors of this paper. Dimensions of the component elements of the joint were defined on the basis of numerical calculations in LS-DYNA system, using finite element method. They also allowed to identify places sensible to damage. Based on the project, the experimental tests have been performed for the joint strength to stretching. The tests performed on the resistance machine showed improper technology and poor quality of welds joining individual elements, particularly the bolt with connecting steel. Results of these tests made the basis for introducing the changes to the project. Repeated tests confirmed their rightness. The final evaluation of quality and usefulness of the prototype articulated joint in the connections of movable protection barrier were defined during the crash tests on the test track of the Certified Research Laboratory of the Research Institute for Roads and Bridges. The crash tests were performed for selected collision criteria (TB11 and TB32), normal restrain level (N2), using three passengers cars. Applied concrete barrier test procedures are in accordance with the requirements of national standards, that make the equivalents of the European standards.
