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, precise, uniform, and comparable profile measurements during construction.

Measurements of profile are made in accordance with ASTM E950. If any part of this practice is in conflict with references made, such as ASTM Standards, this practice takes precedence for its purposes.
