Inertial Profiling (IP) quickly and efficiently assures that all smoothness requirements have been met for the entire surface.

IP uses a device that measures the pavement profile up to highway speeds without the need for road closures. The device uses an accelerometer to form an inertial reference, a laser-height sensor to measure the pavement surface location relative to that reference and a distance-measuring instrument (DMI) and/or GPS to measure the longitudinal distance traveled during the testing.

Once completed, the profiles are upload to the FHWA sponsored ProVAL (Profile Viewing and Analysis) engineering software application allowing for the viewing and analysis of longitudinal pavement profiles in many ways including:
