TRI’s Transportation Testing and Research Division provides a diverse range of high-quality services to public agencies and private entities. Key services include accelerated pavement testing, rut profiling, cyclic plate loading, 

Full-scale Accelerated Pavement Testing

  • TRI’s accelerated pavement tester (APT) applies rolling wheel loads up to 30 kips
  • Controlled test sections can be constructed in TRI’s indoor APT laboratory with a concrete-lined trench 4 ft. deep by 11 ft. wide by 36 ft. long
  • Dual-wheel assembly applies loads with tires rated for high load carrying capacity (e.g., truck traffic)
  • Request more information about the APT equipment and capabilities

Cyclic Plate Load Testing

  • TRI’s cyclic plate load (CPL) testing device accommodates individual test sections that are 7.5 ft. sq.
  • Height is adjustable to accommodate a variety of configurations up to 6 ft.
  • A servo-hydraulic actuator applies the load and is programmable for various load levels and wave patterns to serve paved and unpaved roadways, geosynthetic-reinforced pavements, railways, and more
  • Request more information about the CPL equipment and capabilities

Rut Profiling

  • Portable rut profiler capable of measuring the profile of a road surface for the purpose of calculating rut
  • Characterization of the surface profile
  • Active computer user interface integrated into the hardware
  • The length of the measurement depends on the length of the linear rail  – additional rails can be purchased to accommodate longer spans
  • Rugged laptop to interface with hardware and interpret results
  • Durable boxes to store and transport the system
  • Customizable
  • Manual positioning of device by manually rolling into place
  • Easily assembled, deployed and transported
  • Long-lasting Ni+ batteries
  • Measurement made using laser accurate to +/- 1 mm
  • Detailed profile takes approximately 15 seconds
  • Output stored in electronic files for future analysis if desired
