Inertial Profiler Certification

 

Smooth pavement

Inertial profiler certification program

Objectives

  • To provide a calibration standard against which all inertial profilers can be tested
  • To verify the validity and reliability of data collected by inertial profilers

Operator certification

Any profiling conducted on a MnDOT Pavement Surface Smoothness specification project must be performed by a certified inertial profiler operator. In order to become a certified operator, one must successfully complete an online training course and examination. The certification course and exam are free of charge.

Equipment certification

All inertial profilers used on MnDOT projects must be certified prior to official data collection. Certification is held each spring at the MnROAD Research Facility in Albertville, MN. Operators are required to throughly read MnDOT's Inertial Profiler Certification Procedures before participating in a certification test. Equipment certification is free of charge for contractors with MnDOT paving projects during the current calendar year.
