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.
