PD ISO/PAS 13473-6:2021 PDF Download

PD ISO/PAS 13473-6:2021 is part of a series of standards that addresses the characterization of pavement texture using surface profiles. This specific part of the standard focuses on the verification of the performance of laser profilometers used for pavement texture measurements.

The standard provides methods for checking the performance of laser profilometers in terms of their capability to accurately measure pavement texture. Laser profilometers are contactless devices, typically based on laser point or line triangulation, that are designed for two or three-dimensional measurements. PD ISO/PAS 13473-6:2021 aims to evaluate and ensure the performance of these types of profilometers.

The standard is relevant to manufacturers and suppliers of profilometers, road construction materials, civil engineers, and the construction industry. It emphasizes the importance of pavement texture in influencing factors such as friction, noise, and smoothness. Pavement texture data is commonly used in studies and surveys of pavement surface attributes, including tire/road noise, rolling resistance, skid resistance, and splash and spray.

PD ISO/PAS 13473-6:2021 provides guidelines and recommendations to assist users of laser profilometers in verifying the performance of their equipment. It aims to ensure that the systems perform satisfactorily and can accurately measure pavement texture. The standard also provides information about the limitations and trade-offs of laser profilometer systems, addressing the challenge of incompetent equipment. Its objective is to establish an internationally accepted procedure for evaluating the performance of laser-based equipment used for pavement texture measurements.
