The study concerns a selected road safety barrier consisting of a B-type guiderail, Sigma-100 posts with 2.00 m spacing, bolts and supporting elements, located on a horizontal concave arc having a 150 m radius. In order to meet all the functionality criteria, a composite-foam protective overlay is designed and applied. Two full-scale experimental crash tests were carried out, i.e. TB32/CB, TB32/CBC, where TB32 – crash test defined in the EN-1317 standard, CB – curved barrier without the overlay, CBC – curved barrier with the overlay. The numerical modelling and simulation methodology for crash tests, developed by Klasztorny et al. (2016), is applied. Simulations of the above tests were performed using LS-Dyna v.971 finite element code. All the functionality parameters for the barrier are studied. The results of the simulated tests were compared with those of the experimental tests also using the RSVVP programme. The experimental validation of the numerical modelling and simulation is rated positively. It was proven that the TB32/CB crash test does not meet the criteria imposed on the vehicle motion in the exit box, and for the TB32/CBC crash test, these criteria are met.
