AASHTO R 56 – Standard Practice for Certification of Inertial Profiling Systems

This practice describes a certification procedure for test equipment used to measure a longitudinal surface elevation profile of highways based on an inertial reference system that is mounted on a host vehicle. The minimum requirements stipulated herein are intended to focus on the need for accurate and repeatable profile measurements for construction quality control/quality assurance, acceptance and network-level data collection.

This practice describes minimum performance requirements for inertial profiling systems to be used on Owner-Agency paving projects where a profile-based smoothness specification is applicable and for network data collection programs.
