  • Detection of Delaminated and Cracked Concrete with Unmanned Aerial Vehicles

    The unmanned aerial vehicles or drones provide eyes that reach the sites and parts of structures that are difficult to access. They are very valuable when high bridges with large spans, which would typically require special vehicles, hoists or personnel with climbing skills, are inspected. If a drone carries infrared sensors and high definition lenses with a long focal length, its scope can be extended to non-destructive damage detection. This article presents the results of a study on the use of [...]

  • Safety and Extension of Life Time of Road Bridges

    Road bridges are fundamental infrastructure in all national, regional or local road networks.

Due to this situation, many developed countries are facing a problem related to aging of road bridges. Developing countries have devoted their investment to infrastructure in more recent times and will face similar aging issues in the future.
