Abstract

Summary

Highway road monitoring by means of visual inspection has been and probably will remain standard procedure for many years. However numerous examples of sudden cracks and collapses of the pavement have shown that more efficient methodologies are essential. GPR has been used extensively for this purpose. The survey focuses on the parts of the highway over the embankments that are approaching the bridge from both ways as well as the bridge’s deck. The appearance of a small hole in the pavement of the new part of the highway, only few tenths of meter away from the western edge of the bridge called for immediate evaluation of the extent of the void and inspection for other potentially future failures. In parallel with the inspection for cracks and cavities the investigation aimed to provide insight on the construction of the pavement of the old bridge and the approaching areas and compensate for the lack of realistic cross section. The method of GPR was the ideal method for this task, since it is non-invasive, very fast and very accurate when good approximation on the material’s electromagnetic properties can be achieved ( )
