This practice describes the procedure for operating and verifying the calibration of an inertial profiler. This practice is meant to be performed as a Quality Assurance (QA) test for use with the appropriate smoothness specification for paving operations. It is not meant to be required as a Quality Control (QC) procedure to monitor daily paving operations; however@ this method is recommended when inertial profilers are used for QC testing and for network level data collection. It also provides: ? evaluation procedures for the profiles that are generated@ and ? a methodology for resolution of disputes arising from suspect profiler output.
