AASHTO PP 111-21 PDF Download

The AASHTO PP 111-21 standard aims to establish consistent definitions for terms used in transverse pavement profiling systems. These terms are used in specifications, test methods, standard practices, and quality assurance procedures.

The standard's main objective is to ensure a common understanding and interpretation of the terms within the industry. By providing standardized definitions, it enables effective communication and collaboration among stakeholders involved in transverse pavement profiling.

This standard practice is crucial for the accurate implementation and assessment of transverse pavement profiling systems and ground reference equipment. It supports the development of reliable and consistent measurement techniques, which are essential for evaluating pavement conditions, maintenance needs, and performance.
