The purpose of this paper is to offer an approach to elaboration of technical documentationon the reconstruction of tghe existing protective barriers, as pursuant to the MKS EN 1317 standard, on all the roads in the Republic of North Macedonia. The current situation regarding the protective barriers on the motorways is the following: short protective lengths (shorter than the tested one), unprotected obstacles (non-standards boards, portals, road lamps, concrete pillars, tunnel portals, logs etc.), protection of third persons is not taken into consideration, Inappropriate application of the U.S4 standard (use of aluminum instead of steel profiles, barriers of metal sheets thinner than the standard ones, inappropriate pillars, bolts of lower quality than the prescribed one, larger distance between pillars, thinner anti-corrosion layer etc.) The new EN1317 standard dictates complete coverage of all the above cited shortcomings, regardless of whether positions that do not exist in the previous standard or omissions upon designing or performance are considered. The paper shall present the actual problems identified upon the design with permanent protection and their elimination with the new standard of MKS EN 1317.
