Full title and description

STB DIN EN ISO 13473-1 2021-11 — Characterization of pavement texture by use of surface profiles — Part 1: Determination of mean profile depth. German adoption (DIN) of EN ISO 13473-1:2019 with the corrected version of June 2021; available in German and English.

Abstract

This part of ISO 13473 specifies a test method for determining the mean depth of pavement macrotexture (mean profile depth, MPD) by measuring a surface profile and calculating texture depth from that profile. The procedure describes required instruments, measurement and data-processing steps, uncertainty assessment and reporting. The method is intended for pavement texture assessment for purposes such as skid performance, water drainage, tyre/road noise evaluation and quality control, but it notes limitations for porous or grooved surfaces.

Scope

The standard defines a laboratory and field-applicable procedure to measure surface profiles and to calculate the mean profile depth (MPD) as a descriptor of pavement macrotexture. It specifies the types of test surfaces and instruments applicable, the measurement procedure, data-processing and filtering steps, uncertainty evaluation and the required contents of a test report. The method is geared to macrotexture assessment and is not intended to replace other texture measures for microtexture or detailed megatexture analysis; it also flags interpretation issues for porous and heavily grooved surfaces.

Key topics and requirements

• Definition of MPD (mean profile depth) and related texture terminology.
• Specification of acceptable profilometers and sensors, and instrument calibration requirements.
• Detailed measurement procedure: profile acquisition, sampling lengths and measurement locations.
• Data processing: filtering, spike removal and algorithms to compute MPD from profile data.
• Assessment of measurement uncertainty following ISO/IEC Guide 98-3 (GUM) principles.
• Requirements for test reporting and informative annexes on texture ranges, sampling and special-surface issues.

Typical use and users

Used by highway agencies, pavement engineering and maintenance organizations, road- and airport-runway testing teams, researchers in tyre/road noise and friction, pavement material suppliers and contractors for quality control and acceptance testing. The standard supports specification compliance, performance assessment and comparative texture monitoring.

Related standards

ISO 13473 is a multi-part series; closely related parts and complementary standards include ISO 13473-2 (terminology and basic requirements), ISO 13473-3 (profilometer specification and classification), ISO 13473-4 (spectral/one-third-octave analysis of surface profiles) and other texture/measuring standards such as EN 13036 (patch and profile methods) and ISO 8608 (road roughness / unevenness). These are commonly referenced together when characterizing pavement texture across micro-, macro- and megatexture ranges.

FAQ

Q: What is this standard?

A: It is the DIN-adopted version of EN ISO 13473-1 (designation DIN EN ISO 13473-1:2021-11), which specifies a method to determine mean profile depth (MPD) — a macrotexture descriptor — from pavement surface profiles.

Q: What does it cover?

A: It covers instrument requirements, measurement procedures, data processing (filtering and spike removal), calculation of MPD, uncertainty assessment and test-report content. It focuses on macrotexture; users should consult other parts of the ISO 13473 series for terminology, instrument classification and spectral analysis.

Q: Who typically uses it?

A: Highway and airport agencies, pavement engineers, testers and contractors, researchers in tyre/road interactions and noise, and organisations performing pavement quality control and acceptance testing.

Q: Is it current or superseded?

A: The DIN EN ISO 13473-1:2021-11 adoption is current. It implements ISO 13473-1:2019 (with the corrected version of June 2021) and replaces earlier national adoptions (for example the 2004 edition). Regular reviews are conducted per ISO/DIN procedures.

Q: Is it part of a series?

A: Yes — ISO 13473 is a multipart series addressing pavement texture by surface-profile methods; Part 1 covers MPD, Part 2 covers terminology and requirements, Part 3 covers profilometer specification, Part 4 covers spectral analysis, and other parts address megatexture and related descriptors.

Q: What are the key keywords?

A: Mean profile depth (MPD), pavement macrotexture, profilometer, surface profile, texture measurement, measurement uncertainty, ISO 13473, DIN EN ISO.
