AASHTO PP 107-21 PDF Download

The AASHTO PP 107-21 standard outlines the procedure for evaluating the accuracy and precision of transverse pavement profilers. Specifically, this standard focuses on assessing the vehicle body motion error when the system is subjected to primary ride and wheel hop excitation frequencies.

The objective of this standard is to ensure that transverse measurements obtained from the transverse pavement profilers are accurate and repeatable, which is crucial for both network-level and project-level data collection. It is important to note that in case of any conflicts between this standard and referenced documents, such as ASTM standards, this practice takes precedence.

To comprehensively evaluate and certify the transverse pavement profiler under typical operating conditions, this standard practice should be carried out in conjunction with three other standard practices. These additional practices include PP 106 for static assessment, PP 109 for ground reference and transverse width assessment, and PP 108 for drift mitigation assessment.
