Deflection measurements with Dynatest FALLING WEIGHT DEFLECTOMETER (FWD)

  • Equipped with 9-11 seismic sensors to provide deflection basin caused by controlled load
  • SHRP Reference calibrated by SABS
  • Three fully calibrated and operational FWD’s to meet our customer demand
  • FWD mobility enable us to work across RSA borders in Africa and even on other continents if required.
  • FWD generated data combined with layer thickness can be used to obtain in-situ resilient E-moduli of a pavement
  • structure which in turn can be used in a structural analysis to determine bearing capacity, estimate expected life and calculate an overlay requirement.

Friction measurements with Findlay Irvine GRIPTESTER Mark II and Douglas MuMeter Mark VI

  • For use on Roads & Airport runways
  • Fixed slip device enabling continuous measurements
  • Horisontal (Drag) and vertical (Load) forces are measured continuously
  • Measuring tyre is ASTM Type A and quality is strictly controlled
  • PIARC calibrated to measure IFI

Profiling with Dynatest Road Surface Profiler 5051 Mark III & IV

  • IRI to class 1 standard as per ASTM E950.
  • Rutting Profiles taken with 17 lasers.
  • DGPS allows easy integration of GIS.
  • Integrated digital photos every 10m back and front.
  • Real time data processing.
  • All traffic speeds.
  • Network, Project and Quality Acceptance Surveys (for Penalty/Bonus Situations)
