AASHTO PP 106-21 PDF

This practice describes the procedure to assess the specifications, accuracy, and precision of the sensor system used on transverse pavement profilers (TPP) in static mode. The particular specifications which will be assessed are transverse spacing, transverse width, vertical spacing, straightness error, vertical measurement error, and transverse measurement error.
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 ground reference and transverse width assessment, see PP 109; for body motion assessment, see PP 107; and for assessment of drift mitigation, see PP 108.
