Full title and description

STB DIN EN ISO 13473-1 E 2017-08 — Characterization of pavement texture by use of surface profiles — Part 1: Determination of mean profile depth (prEN / draft version published August 2017). This document specifies a profile-based procedure to determine the Mean Profile Depth (MPD) — a measure of the macrotexture depth of paved surfaces — as an alternative to volumetric (sand/glass-bead) methods.

Abstract

This part of the ISO 13473 series describes how to record a surface profile of a pavement and how to calculate the Mean Profile Depth (MPD) from that profile. The method is intended to provide a robust, repeatable indicator of macrotexture depth (affecting tyre/road grip, noise and rolling resistance) that is largely insensitive to microtexture and small-scale irregularities. The draft identified by the 2017-08 designation later fed into the ISO 13473-1:2019 / corrected 2021 national adoptions.

General information

• Status: prEN / draft (August 2017). The work was advanced as a committee draft in 2017 and the final ISO edition was published later; national adoptions (e.g. DIN) appear in 2021.
• Publication date: August 2017 (prEN / draft). Specific draft release date commonly cited: August 2017 (2017-08).
• Publisher: draft circulated under the EN/ISO adoption process (ISO/DIN context; national sales and adoption handled by DIN and by national standards bodies).
• ICS / categories: 17.140.30 (Noise emitted by means of transport); 93.080.20 (Road construction materials).
• Edition / version: E 2017-08 (prEN / draft designation). Note: ISO 13473-1 was finalized as ISO 13473-1:2019 (with corrected/national adoptions in 2021).
• Number of pages: Drafts and national translations commonly list ~54 pages for the prEN/draft. The later DIN/ISO 2021 national adoption is recorded with ~54–58 pages depending on national front matter.

Scope

This document defines a profile-measurement procedure to determine the Mean Profile Depth (MPD) as a descriptor of pavement macrotexture. It covers acquisition of a representative surface profile (contact or non-contact profilometers), processing of the profile to remove form and noise as required, calculation of MPD from the processed profile, and reporting requirements to ensure comparability of results. The method is intended for paved road and airfield surfaces and is focused on macrotexture (wavelengths roughly 0.5 mm to 50 mm).

Key topics and requirements

• Definition and determination of Mean Profile Depth (MPD) from surface profiles.
• Profile acquisition: recommended profilometer types, sampling intervals and orientation (longitudinal/transverse) for representative measurements.
• Pre-processing of raw profiles: removal of form, filtering and handling of spikes/noise to isolate texture wavelengths of interest.
• Calculation algorithm for MPD (segmentation of the profile, baseline/mean removal, averaging procedures).
• Reporting and documentation: measurement conditions, instrument classification, profile statistics and uncertainties.
• Comparability with volumetric (sand/glass-bead) texture depth methods and guidance on interpretation for friction/noise analyses.

Typical use and users

The standard (draft and its subsequent final national adoptions) is used by highway agencies, pavement engineers, acoustic specialists, road-safety investigators, equipment manufacturers (profilometers, laser sensors) and testing laboratories. Typical applications include routine network texture monitoring, quality control at construction handover, research into tyre/road noise and friction performance, and specification of contract acceptance criteria.

Related standards

ISO 13473 is a multipart series. Key related parts include ISO 13473-2 (terminology and basic requirements for profile analysis) and ISO 13473-3 (specification and classification of profilometers). Subsequent parts and technical reports cover spectral analysis (part 4) and megatexture (part 5) as well as verification methods for laser profilometers (part 6 / PAS). The draft/prEN 2017 work on part 1 was later reflected in ISO 13473-1:2019 and national adoptions (e.g. DIN EN ISO 13473-1:2021).

FAQ

Q: What is this standard?

A: It is the draft/national-designation STB DIN EN ISO 13473-1 E 2017-08 (prEN) for Part 1 of the ISO 13473 series, describing how to determine Mean Profile Depth (MPD) from pavement surface profiles.

Q: What does it cover?

A: It covers measurement and processing of surface profiles and the calculation and reporting of MPD as an indicator of pavement macrotexture depth; intended uses include texture monitoring, QC, noise and friction assessment.

Q: Who typically uses it?

A: Road authorities, pavement and traffic engineers, acoustic specialists, test laboratories and manufacturers of profilometers and road-measurement systems.

Q: Is it current or superseded?

A: The 2017-08 designation refers to a draft/prEN stage. The final international edition ISO 13473-1 was published in 2019 and corrected/adopted as national standards (e.g. DIN EN ISO 13473-1) in 2021; users should refer to the latest national adoption (DIN EN ISO 13473-1:2021-11 or ISO 13473-1:2019) for the current, authoritative text.

Q: Is it part of a series?

A: Yes — ISO 13473 is a multipart standard covering pavement texture by profile methods (parts 1–6, with parts 2 and 3 established earlier and later parts addressing spectral analysis, megatexture and verification).

Q: What are the key keywords?

A: Mean Profile Depth (MPD), pavement/macrotexture, surface profile, profilometer specification, profile processing, texture measurement.
