Ground Penetrating Radar (GPR)

Oscorp Engineering acquired the world’s most advanced Ground Penetrating Radars. Pavement layer thicknesses could be scanned at high speeds up to 100 Km/hr. This system can collect up to four channels of data simultaneously with uncompromised performance.

GPR testing is a geophysical non-destructive testing that uses radar pulses electromagnetic waves) to image the subsurface. Depending on the depths needed, the GPR pulses could be tailored to meet target depth levels. For example a 2 GHz GPR antenna will target the top 700mm of pavement with high resolution while a 200 MHz waves could travel to depths up to 18 meters.

As the basis of a high-speed data collection system, the GPR ideal for measuring pavement layer thickness, detection of cavities, airport runway assessment, bridge deck inspection, detection of ballast and utility detection. The GPR system delivers high-speed data collection-capable of more than 1,375 scans/second, per channel with up to 500 GB data storage.

Examples of GPR Uses in:

  • Pavement management.
  • Pavement performance and remaining life.
  • Setting maintenance and rehabilitation priorities.
  • Main input in overlay design.
  • Distress Forensics.
  • As built thickness construction.
  • Locating buried concrete pavements.
  • Deterioration in asphalt covered bridge decks.
  • Pavement Rehabilitation (identifying changes).
  • Defects in Hot Mix layers (air voids, trapped moisture).
  • Evaluating pavement structure after milling.
  • Areas of high moisture contents i.e. seepage.
