Abstract (EN): Several researchers have developed a thematic approach related with the need to improve safety management in the maintenance works on motorways in operation. The use of instruments linked to efficiency and effectiveness can be a possible solution for this challenge. The main objective of the present research is to prove the potential of identifying the main risky activities and safety measures contained in the A area curve linked to the Pareto's concepts to show that these safety measures can reduce the risk level of the most dangerous activities. The selected methodology was a DELPHI panel formed by safety experts from different areas of road engineering. The statistic treatment was performed with the IBM SPSS Statistics 24 software. The results show that it was possible to identify the 38 most dangerous risks linked to the most dangerous activities and the 44 most efficient and effective safety measures to prevent/avoid those risks. This research concluded that (i) the risk level decreases with the adopted safety measures and (ii) the identified risk activities and the associated safety measures represent the A area from an ABC curve linked to the Pareto's concept. These conclusions present an obvious relevance to the decisions about maintenance works on motorways.
