Over the years, there have been some changes regarding road vehicle restraint systems, especially concerning the requirements and the selection criteria for its implementation.

    In Portugal, the guidance manual that set the requirements for the safety barriers in accordance with the EN1317 was published in 2010. At that time, most of the Ascendi’s network was already constructed and under operation, being the safety barriers applied based on the national requirements available at the time of the project.

    In order to evaluate the network compliance with the current established requirements, Ascendi carried out an upgrading program (Ascendi’s Safety Barriers Upgrading Program) that started in 2018 and will run until 2023.

    This paper will cover the Upgrading Program that was established, going through the challenges of its implementation that included the development and certification of a brand-new safety barrier for bridges with a 30 cm curb in cooperation with Road Steel Engineering, S.L.
