Experiences and practices from application of rockfall remedial works at MKD national road network

We present a slightly abridged and adapted translation of the report “Experiences and practices from application of rockfall remedial works at MKD national road network” (Jovanovski et al., 2023), which was made by Macedonian engineering surveyors at the National transport infrastructure conference with international participation in October 2023 in Nessebar (Bulgaria). This report was also published as an article in the journal “Materials Science and Engineering” by the publishing company of the British scientific society “Institute of Physics” (IOP) that is now virtually international. It is an open access article under the CC BY 3.0 license that allows it to be distributed, translated, adapted, and supplemented, provided that the types of changes are noted and the original source is referred to. In our case, the full reference to the original paper (Jovanovski et al., 2023) for the presented translation is given in the end. Rockfalls, landslides and floods continue to have a growing share in the overall damages and losses, influencing considerably the national budget. Recent experiences and practices related to application of stabilization measures and remediation of rockfall zones along MKD national road network are presented in the article. Analyses are based on case histories where the prognosis of geotechnical conditions is a key element in definition of remedial measures for rock slopes. Some issues related with the Consequence Classes, as suggested in Eurocode 7, and the concepts of the Acceptable Level of Risk are presented. Proposals in definition of the Acceptable Level of Risk, through combining the Probability of Failure, Reliability Index and Consequence Classes, are given in the article. These findings can help in development and/or improvement of rockfall, landslide and flood risk management strategies.
