Abstract:Across the United States, state and local transportation agencies are tasked with collecting transverse profile measurements. Collection of the data is carried out with a variety of systems that operate at the prevailing speed limit. With the wide range of systems used to collect data it is critical that transportation agencies know the system used to collect the data is accurate and the reported results are comparable to other measurement systems. This report summarizes the development of standard practices which should be conducted to calibrate, certify, and verify transverse pavement profiling equipment used to collect rut depth, cross-slope, and/or edge/curb detection data. Through implementation of the standard practices and requirement statements presented herein transportation agencies will have the ability to: identify the accuracy and precision of transverse pavement profile measurements, identify if two or more measurement systems are providing results within tolerances, and determine if measurements taken at different times are consistent.
