This practice describes the procedure to assess the accuracy and precision of the transverse pavement profiler (TPP) when the system is excited at the primary ride and wheel hop excitation frequencies. The particular specification which will be assessed is vehicle body motion error.
The minimum requirements 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 ground reference and transverse width assessment, see PP 109; and for assessment of drift mitigation, see PP 108.
