Pavement Testing Equipment

Gilson offers a versatile line of Pavement Quality Testing Products for every step of the process, from the monitoring of asphalt placement and testing of strength and permeability properties to the retrieval of drilled core specimens.


  • Core Drilling and Sawing equipment is used in preparing asphalt cores for laboratory testing. Core Drilling Machines, Asphalt Diamond Coring Bits and Expander Sets for Open-Head Asphalt Coring Bits are used in drilling asphalt cores and meet ASTM and AASHTO standards. Cores are retrieved using Tongs or Extractors, while Masonry Saws trim the specimen to testing size.

  • NCAT Asphalt Field Permeameter determines the water flow rate through asphalt pavement.

  • Laboratory Asphalt Permeameters measure hydraulic conductivity of saturated 4in and 6in diameter asphalt cores and laboratory compacted samples.

  • FLIR® C2 Thermal Imaging System is a pocket-sized thermal camera that finds hidden heat patterns.

  • FLIR® Infrared Thermal Imaging Cameras offer rapid detection of problem areas by quickly highlighting temperature gradients.

  • FLIR® Imaging IR Thermometer enables easy visualization of heat patterns on a 2in display.

  • Basic Thermal Imaging Camera features a 3.5in display and and five color display palettes to select from. Images are stored for download to user's computer.

  • Asphalt Depth Gauge accurately measure thickness to confirm compliance with design parameters.

  • Benkelman Beam measures deflection under heavy wheel loads to estimate pavement performance and subgrade strength.

  • Digital Calipers are an effective tool in pavement quality testing, and provide accuracy and precision in specimen measurements. Available in 0-6in (152mm) and 10-12in (305mm) ranges.
