ABSTRACT
In this paper principal results of recent years’ experience of inspection of hundreds of highways retaining walls and geotechnical sites are critically presented. Inspection activities have been carried out on different geotechnical works, along Italian highways. These activities allowed to build an accurate damage database whose main features and statistics are discussed below. Then, a comparison between different inspection checklist and procedures developed by the highways management company is analyzed as current Italian practice and a new proposal for a better and more efficient inspection procedures. Besides, possible application of UAS and AI as supporting tools for visual inspections are pointed out.
