Characterization of pavement texture by use of surface profiles - Part 5: Determination of megatexture (ISO 13473-5:2025)

Characterization of pavement texture by use of surface profiles - Part 5: Determination of megatexture (ISO 13473-5:2025)

This document specifies a procedure for determining the magnitude of pavement surface megatexture by measuring the surface profile and calculating a megatexture descriptor from this profile. The technique is designed to give meaningful and accurate measurements and descriptions of pavement megatexture for various purposes, such as for the prediction of the acoustic quality of the pavement or the assessment of the rolling resistance.
Since there is an overlap between megatexture and the surrounding ranges, megatexture descriptors unavoidably have a certain correlation with corresponding measures in those ranges. This document specifies measurements and procedures which are in relevant parts compatible with those in ISO 13473-1[4], ISO 8608[6] and EN 13036-5[7].

Charakterisierung der Textur von Fahrbahnbelägen unter Verwendung von Oberflächenprofilen - Teil 5: Bestimmung der Megatextur (ISO 13473-5:2025)

Dieses Dokument legt ein Verfahren zur Bestimmung des Betrags der Megatextur einer Fahrbahnoberfläche durch Messung des Oberflächenprofils und Berechnung eines Megatexturdeskriptors aus diesem Profil fest. Die Technik ist so ausgelegt, dass sie aussagekräftige und genaue Messungen und Beschreibungen der Megatextur der Fahrbahn für verschiedene Zwecke wie die Vorhersage der akustischen Güte der Fahrbahn oder die Beurteilung des Rollwiderstands ergibt.
Da es zwischen der Megatextur und den angrenzenden Bereichen eine Überlappung gibt, weisen Megatexturdeskriptoren unvermeidlich eine gewisse Korrelation mit den entsprechenden Maßgrößen in diesen Bereichen auf. Dieses Dokument legt Messungen und Verfahren fest, die in den relevanten Bereichen kompatibel mit denen von ISO 13473 1 [4], ISO 8608 [6] und EN 13036 5 [7] sind.

Caractérisation de la texture d'un revêtement de chaussée à partir de relevés de profils de la surface - Partie 5: Détermination de la mégatexture (ISO 13473-5:2025)

Le présent document spécifie un mode opératoire permettant d’évaluer la mégatexture d'une surface de revêtement en mesurant le profil de surface et en calculant un indicateur de mégatexture à partir de ce profil. La technique a été élaborée pour donner des mesures et des descriptions significatives et précises de la mégatexture du revêtement pour différentes utilisations, par exemple pour prédire la qualité acoustique du revêtement ou pour évaluer la résistance au roulement.
Du fait du recouvrement entre la mégatexture et les domaines voisins, les indicateurs de la mégatexture présentent inévitablement une certaine corrélation avec les mesures correspondantes de ces autres domaines. Le présent document spécifie des mesurages et des modes opératoires qui sont dans leurs différents aspects aussi compatibles que possible avec ceux de l'ISO 13473-1[4], de l'ISO 8608[6] et de l'EN 13036-5[7].

Acoustics - Measurement of the influence of road surfaces on traffic noise - Part 1: Statistical Pass-By method (ISO 11819-1:2023)
SIST EN ISO 11819-1:2023

This document specifies a method of comparing traffic noise on different road surfaces for various compositions of road traffic for the purpose of evaluating different road surface types. Sound levels representing either light or heavy vehicles at selected speeds are assigned to a certain road surface. The method is applicable to traffic travelling at constant speed, i.e. free-flowing conditions at posted speeds of 50 km/h and upwards. For conditions where traffic is not free flowing, such as at junctions and where the traffic is congested, the method is not applicable.
A standard method for comparing the noise characteristics of road surfaces gives road and environment authorities a tool for establishing common practices or limits regarding the use of road surfaces meeting certain noise criteria. However, it is not within the scope of ISO 11819 (all parts) to suggest such criteria.
The statistical pass-by (SPB) method is suitable for use for the following main purposes:
—    to classify road surfaces according to their influence on traffic noise (surface classification);
—    to assist in verifying conformity of production of road surfaces;
—    to evaluate acoustic performance of road surfaces throughout operation relative to new condition;
—    to evaluate the influence of different road surfaces on traffic noise at sites irrespective of condition and service time;
—    to evaluate acoustic performance of a road surface relative to a reference surface.
Due to practical restrictions, the method cannot be applied at all possible locations. However, the backing board method can allow some locations to be tested that were not previously acceptable.
Clause 5 gives a general description of the SPB method.

Characterization of pavement texture by use of surface profiles - Part 1: Determination of mean profile depth (ISO 13473-1:2019, Corrected version 2021-06)
SIST EN ISO 13473-1:2019

This document describes a test method to determine the average depth of pavement surface macrotexture (see Clause 3) by measuring the profile of a surface and calculating the texture depth from this profile. The technique is designed to provide an average depth value of only the pavement macrotexture and is considered insensitive to pavement microtexture and unevenness characteristics.
The objective of this document is to make available an internationally accepted procedure for determination of pavement surface texture depth which is an alternative to the traditionally used volumetric patch technique (generally using sand or glass beads), giving comparable texture depth values. To this end, this document describes filtering procedures that are designed to give the best possible representation of texture depths determined with the volumetric patch method[13].
Modern profilometers in use are almost entirely of the contactless type (e.g. laser, light slit or light sheet, to mention a few) and this document is primarily intended for this type. However, this does not exclude application of parts of it for other types of profilometers.
This ISO 13473 series has been prepared as a result of a need identified when specifying a test surface for vehicle noise measurement (see ISO 10844:2014[6]). Macrotexture depth measurements according to this document are not generally adequate for specifying test conditions of vehicle or traffic noise measurements, but have limited applications as a supplement in conjunction with other ways of specifying a surfacing.
This test method is suitable for determining the mean profile depth (MPD) of a pavement surface. This MPD can be transformed to a quantity which estimates the macrotexture depth according to the volumetric patch method. It is applicable to field tests as well as laboratory tests on pavement samples. When used in conjunction with other physical tests, the macrotexture depth values derived from this test method are applicable to estimation of pavement skid resistance characteristics (see e.g. Reference [15]), estimation of noise characteristics and assessment of the suitability of paving materials or pavement finishing techniques.
The method, together with other measurements (where applicable), such as porosity or microtexture, can be used to assess the quality of pavements.
This document is adapted for pavement texture measurement and is not intended for other applications. Pavement aggregate particle shape, size and distribution are surface texture features not addressed in this procedure. The method is not meant to provide a complete assessment of pavement surface texture characteristics. In particular, it is known that there are problems in interpreting the result if the method is applied to porous surfaces or to grooved surfaces (see Annex B).
NOTE Other International Standards dealing with surface profiling methods include, for example, References [1], [2] and [3]. Although it is not clearly stated in these, they are mainly used for measuring surface finish (microtexture) of metal surfaces and are not intended to be applied to pavements.

Acoustics - Measurement of the influence of road surfaces on traffic noise - Part 2: The close-proximity method (ISO 11819-2:2017)
SIST EN ISO 11819-2:2017

ISO 11819-2:2017 specifies a method of evaluating different road surfaces with respect to their influence on traffic noise, under conditions when tyre/road noise dominates. The interpretation of the results applies to free-flowing traffic travelling on essentially level roads at constant speeds of 40 km/h and upwards, in which cases tyre/road noise is assumed to dominate (although in some countries it is possible that tyre/road noise does not dominate at 40 km/h when the proportion of heavy vehicles is high). For other driving conditions where traffic is not free-flowing, such as at junctions or under heavy acceleration, and where the traffic is congested, the influence of the road surface on noise emission is more complex. This is also the case for roads with high longitudinal gradients and a high proportion of heavy vehicles.
A standard method for comparing noise characteristics of road surfaces gives road and environment authorities a tool for establishing common practices or limits as to the use of surfacings meeting certain noise criteria. However, it is not within the scope of this document to suggest such criteria.
ISO 11819-1 defines another method: the statistical pass-by (SPB) method. The close-proximity (CPX) method specified in the present document has the same main objectives as the SPB method, but is intended to be used specifically in applications that are complementary to it, such as:
-      noise characterization of road surfaces at almost any arbitrary site, with the main purpose of checking compliance with a surface specification (an example for conformity of production is suggested in Reference [1]);
-      checking the acoustic effect of maintenance and condition, e.g. wear of and damage to surfaces, as well as clogging and the effect of cleaning of porous surfaces;
-      checking the longitudinal and lateral homogeneity of a road section;
-      the development of quieter road surfaces and research on tyre/road interaction.
NOTE          This document does not describe the conditions of application for formal purposes of the measurement with the CPX method. Such conditions may be defined in other standards or legal texts. However, suggestions for the applicability of ISO 11819-1 and this document are provided in Annex D.
Measurements with the CPX method are faster and more practical than with the SPB method, but are more limited in the sense that it is relevant only in cases where tyre/road noise dominates and power unit noise can be neglected. Furthermore, it cannot take heavy vehicle tyre/road noise into account as fully as the SPB method can, since it uses a light truck tyre as a proxy for heavy vehicle tyres and does not take power unit noise into account.
The CPX method specified in this document is intended to measure the properties of road surfaces, not the properties of tyres. If the method is used for research purposes, to provide an indication of differences between tyres, the loads and inflations would normally be adjusted to other values than specified in this document.

Ambient air - Method for the determination of the concentration of nitrogen dioxide by diffusive sampling
SIST EN 16339:2025

This document specifies a method for the sampling of NO2 in ambient air using diffusive sampling followed by extraction and analysis by colourimetry or ion chromatography (IC). It can be used for the NO2 measurement in a concentration range of approximately 3 µg/m3 to 130 µg/m3 [12]. A sample is typically collected for a period of 1 to 4 weeks [14], with exposure periods depending on the design of the samplers and the concentration levels of NO2.
Several sorbents can be used for trapping NO2 in ambient air using a diffusive sampler [15]. This document specifies the application of triethanolamine as the reagent.
This document describes the application of a tube-type sampler (with either a cylindrical or a slightly conical tube), a badge-type sampler and a radial-type sampler.
The relative expanded uncertainty of NO2 measurements performed using these tube-type diffusive samplers can potentially be lower than 25 % for individual measurements. When aggregating results to form annual average values, the relative expanded uncertainty can be further reduced to levels below 15 % due to the reduction of random effects on uncertainty [9].
NOTE   NO2 passive samplers are also employed to measure NOx with the addition of an oxidant to convert ambient NO into NO2. A second NO2 sampler is also deployed without the oxidant and the concentration of NO is determined from the difference of the two samplers [16].
