Towards the Resilience of Attica Region’s Provincial Road 3 in Greece, Due to Slope Failure by Applying Civil Engineering Techniques and a Semi-Quantitative Assessment Approach

Slope failures represent a major threat to human life and infrastructure worldwide, and they often lead to significant disruptions of economic and environmental systems. Landslide mitigation works, which are used to retrieve the damaged (from the landslide) environment, sometimes lack methodologies to integrate resilience into infrastructure projects economically and sustainably. The necessity of developing resilience in civil engineering technical works is getting more obvious since the outcomes from natural disasters, such as those of landslides and floods become more frequent since 2000 and onwards. In this direction, this article aims to describe slope failure mitigation measures through a resilience framework through a case study from a road adjacent to a local stream in the Region of Attica (Greece). A geological-geotechnical study was carried out in the context of the restoration of the road surface and the stability of the stream slopes. The results of the geotechnical study and the mitigation measures executed under the implementation of a resilience approach are presented. The purpose of this article is to describe the process of implementing aspects of resiliency into the civil engineering technical works and to evaluate the effectiveness of implemented strategies for improving the resilience of infrastructure.
