This practice describes minimum performance requirements for inertial profilers to be used for quality control/quality assurance (QC/QA) of surface smoothness on Owner-Agency paving projects where the profile-based smoothness construction specification is applicable.

The practice describes a certification procedure for test equipment used to measure a longitudinal surface profile based on an inertial reference system that is mounted on a transport vehicle. The minimum requirements stipulated herein are intended to address the need for accurate and repeatable profile measurements during construction.
