Fast – testing is now done at highway speeds (45 mph)
Objective – based on statistical state-of-the-art analysis
Reliable – hardware is manufactured to military standards and quality requirements (Through 10 years of research a proven technology for the military and researchers has developed step frequency (sf) ground-penetrating-radar (SF-GPR). Data analysis is proven and repeatable through calibrated and verified testing over 10 years of research and 2 years of practitioner involvement at MD SHA
Low-Cost Evaluation – savings to will be at least 75 % of traditional assessments
Low impact to traveling public – traditional methods – days to weeks of lane closures, but with SF=GPR there are no restrictions to traffic. Bridge decks can be evaluated at highway speeds (45 mph) with no lane closures.
Other applications of SF-GPR transportation infrastructure assessments:
- Evaluation of concrete runways and pavements
- Obtaining a true assessment of concrete bridge decks hidden by asphalt overlays.
- identifying and locating of other critical infrastructure assets such as underground utilities
- identifying voids from mines, failing drainage structures, Karst geology sink holes, etc
- tunnel ceiling, wall and floor evaluation
