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
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 MnDOT's Pavement Surface Smoothness Specification training. This online course, which takes roughly 1.5 hours to finish, is free of charge. Although the training was designed for contractors who conduct pavement profiling on a MnDOT project, it is available to everyone.
