Geotechnical Infrastructure Observation and Auscultation Manual

Road infrastructure networks have a major social and economic role in the development of countries. During the Operation and Maintenance (O&M) period of these structures, their integrity must be promoted, ensuring the safe circulation of users and the service levels established contractually [1]. In order to fulfill the described goals, Ascendi, with the support of specialist consultants in the area, proposes to develop innovative solutions for the management, conservation and maintenance of road geotechnical structures. The innovation in the methodology of auscultation and observation of walls and slopes (W&S) results from the development and integration of a mobile platform for sustainable management of road structures (SustIMS) [2]. This tool allows monitoring of the evolution of the maintenance and conservation states of W&S, knowledge that allows the Asset Management Team to take preventive decisions regarding the sustainable management of W&S, always aiming at safety in circulation and optimization of maintenance costs.
