AASHTO PP 109:2021 Standard Practice for Assessment of Highway Performance of Transverse Pavement Profiling Systems.
This practice describes procedures to assess the accuracy and precision of the transverse pavement profiler (TPP) under typical dynamic operation. The particular specifications which will be assessed are: transverse measurement spacing, effective transverse width, longitudinal measurement spacing, and vertical measurement error.
In addition to the TPP specifications, the TPP will be evaluated on the following deformation parameters: rut depth, cross slope, vertical magnitude of an edge/curb. and transverse location of an edge/curb. Evaluations will be performed by comparing the resulting TPP deformation parameters to ones calculated from ground reference data conforming to PP 110.
The minimum requirements stipulated herein arc 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 assessment of drift mitigation, see
PP 108.
This practice does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of’ this practice to establish appropriate saf’ety and health practices and determine the applicability of regulatory limitations related to and prior to its use.
