AASHTO PP 106-21 PDF Download

AASHTO PP 106-21 is a standard practice that outlines the procedure for assessing the static performance of transverse pavement profiling systems (TPP). The main focus of this standard is to evaluate the specifications, accuracy, and precision of the sensor system used in TPPs when operated in a static mode.

The specific parameters that are assessed include transverse spacing, transverse width, vertical spacing, straightness error, vertical measurement error, and transverse measurement error. These parameters are crucial for ensuring accurate and repeatable transverse measurements, which are necessary for both network- and project-level data collection.

It should be noted that if any conflicts arise between this standard practice and any referenced documents, such as ASTM standards, this practice takes precedence for its intended purposes.

AASHTO PP 106-21 is designed to be used in conjunction with three other standard practices in order to fully assess and certify the TPP under typical operating conditions. These include PP 109 for ground reference and transverse width assessment, PP 107 for body motion assessment, and PP 108 for drift mitigation assessment.
