Inertial Profiler Certification


Smooth pavement

Inertial profiler certification program


  • 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

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 thoroughly 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.

Operator certification

Any profiling conducted on a MnDOT project must be performed by a certified inertial profiler operator. To become a certified operator, one must successfully complete classroom training taught by MnDOT. The 2016 operator certification course, which is free of charge and roughly half a day in length, can be scheduled for either April 26 or 28. This training is offered only to contractors who anticipate conducting pavement profiling on a MnDOT project in 2016. In 2017 and beyond, an online version of the training will be offered.
