Information regarding the thickness and quantity of the existing surface is of utmost importance for taking up road repairs or road quality checks. Such inspection is also required in many circumstances to check the claims of road contractors.  Georadar, as applied to the evaluation of road surfaces, allows the efficient and precise recording of bitumen thickness.  Results are entirely digital, and hence this information can easily be imported into a road management software suite for further analysis.

Recently there has been an increase in the use of concrete as a road surface, principally because they are much more durable.  However, repairs of these surfaces are much more costly than those of bitumen surfaces.  Therefore it is very important to target only those areas where work is needed, in order to keep the budget under control.  The georadar technique allows the mapping of surface deterioration to be carried out efficiently and with precision.  Whether it is for bridges, roads, or multi-level parking structures, with or without a bitumen layer, this technique has proven its worth.
