Latest techniques used to help conserve ancient bridges

Researchers from the Applied Geotechnology Group at the University of Vigo in Spain are using the latest technology to study 80 Roman and medieval bridges to determine the original construction of the bridges and the best ways to conserve them.

The team uses non-destructive technologies such as ground-penetrating radar, a laser scanner and mathematical models to evaluate the bridges and detect unknown structural and geometric details, including cracks, in the structures. According to Dr. Mercedes Solla, "all this information is of historic interest, but it is also useful to civil engineers so that they can plan conservation, improvement and restoration measures in these types of infrastructures."
