Phạm vi áp dụng / Scope of standard

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.

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

This practice does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this practice to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations related to and prior to use.
