本规程描述了操作和验证惯性仿形系统校准的程序。本规程旨在作为质量控制/质量保证（QC/QA）测试，与适当的平整度规范一起用于铺路操作和网络级数据收集。它不是为了作为QA程序来监控日常铺路操作；然而，当惯性剖面系统用于QC测试时，建议使用。

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.
