This practice describes the procedure for operating and verifying the calibration of an inertial profiling system. This practice is meant to be performed as a quality control/quality assurance (QC/QA) test for use with the appropriate smoothness specification for paving operations and for network-level data collection. It is not meant to be required as a QA procedure to monitor daily paving operations; however, it is recommended when inertial profiling systems are used for QC testing. This standard was formerly designated as provisional standard PP 50.
