Workshop 15 - New inspection and rehabilitation techniques for bridges

Thursday, October 5 14:30 - 18:00
Chair: Gonzalo Aria Hofman, Spain, Spanish-speaking Secretary TC 4.2 , and Pierre Gilles, Belgium, French-speaking Secretary TC 4.2
Room: Club E, 1st floor

Bridge inspection, repair and rehabilitation form an essential part of bridge management. New technologies such as remote sensing and the use of a variety of sensors have the potential to significantly improve the quality of the results of structural inspections. On the other hand, aging infrastructure with limited functional capacity pose a major problem in terms of maintaining mobility for the traveling public as well as the transportation of freight and services. Identification of new repair and rehabilitation materials can accelerate and improve the repair and rehabilitation of bridges under traffic. In addition, new technologies and construction methods can also be applied to repair or rehabilitate aging bridges under traffic. For these reasons, this workshop will be organized into two sessions titled “New Inspection methods” and “Assessment and Rehabilitation”.
