Regular inspection and maintenance of road and rail networks can cause massive disruption to private and commercial traffic which in turn can lead to revenue loss. For regular inspections, non-destructive test methods such as Ground Penetrating Radar may provide a quick and inexpensive means to establish whether a structure is still in a serviceable condition or not. The results from these investigations can improve the quality of information by eliminating the subjectivity associated with current inspection techniques.
