AASHTO PP 108-21
Transverse pavement profiling (TPP) systems that provide global positions of road surfaces are often susceptible to drift in the estimate of the global position over time. This practice describes the procedure to assess the amount of drift present in localization systems used in TPPs.
The minimum requirements stipulated herein are intended to focus on the need for accurate and repeatable transverse measurements for network and project level data collection.
If any part of this practice is in conflict with referenced documents, such as ASTM Standards, this practice takes precedence for its purposes.
This standard practice is intended to be conducted in conjunction with three other standard practices to fully assess and certify the TPP in typical operating conditions. For static assessment, see PP 106; for body motion assessment see PP 107; and for ground reference and transverse width assessment see PP 109.
