This European Standard specifies the mathematical processing of digitized longitudinal profile measurements to produce evenness indices. The document describes the calculation procedure for the International Roughness Index (IRI), Root Mean Square (RMS) and Longitudinal Profile Variance (LPV) from three separate wavelength bands and the σWLP and ΔWLP from the Weighted Longitudinal Profile (WLP).
The purpose of this document is to provide a standard practice for calculating and reporting estimates of road evenness from digitized longitudinal profiles. Other aims with the standard are to facilitate the comparison of evenness measurement results carried out with different profiling instruments in European countries.
The evenness range covered in this standard is defined as the wavelength range 0.5 m to 50 m. It should be noted that both shorter and longer wavelengths can also influence the driving comfort but those are not covered in this standard.
The quantified evenness indices derived from the standard are useful support for pavement management systems. The output can also be used for type approval and performance control of new and old pavements. The indices can be used on rigid, flexible and gravel road surfaces.
The standard doesn´t define from what position on the road the longitudinal profile should be obtained.
The derived indices are portable in the sense that they can be obtained from longitudinal profiles measured with a variety of instruments.

This Technical Specification describes a method for determining the wet road skid resistance of a surface by measurement of the longitudinal friction coefficient LFCN. The described method is also used to determine the skid resistance on a surface covered by ice or snow.
The method provides friction coefficient measurements of the pavement by using an electrically braked test wheel.
ViaFriction can operate in the following modes:
- Fixed slip: The slip ratio is fixed. The slip ratio can be set to a value from 1 % to 75 %.
- Fixed slip speed: The slip speed is fixed. The slip speed has to be lower than the vehicle speed.
- Variable slip: The test wheel is braked from 0 % to 75 % slip ratio recording F 30, F 60 and the slip ratio/friction curve.
The test tyre is dragged over a pre-wetted pavement under controlled speed conditions while the test tyre is parallel to the direction of motion and perpendicular to the pavement. Skid resistance measurement on winter roads do not require pre-wetted pavement.
To determine the macrotexture of the pavement surface a laser system can be added. This system is placed in front of the towing vehicle in order to measure the macrotexture (mean profile depth - MPD) on dry pavements and on the same path as the skid resistance measurement is done. The standard for this measurement and the device is described in EN ISO 13473 1.

This Technical Specification describes a method only used on airports for determining the skid resistance of pavements by measurement of the longitudinal friction coefficient LFCI.
The method provides a measure of the wet skid resistance properties of a bound surface by measurement of the longitudinal friction coefficient using a trailer with a standard slip ratio of 15 %. The slip ratio can be chosen between 0 % and 100 % for research application.
The test tyre is dragged over a pre wetted pavement under vertical force and constant speed conditions while the test tyre is parallel to the direction of motion.
This Technical Specification covers the operation of the IMAG device.
The skid resistance of a pavement is determined by friction measurements at different speeds. Tests can be performed between 40 km/h and 120 km/h but standard test speeds are 40 km/h, 65 km/h and 95 km/h. Low speed measurements asses the microtexture while high speed measurements asses the macrotexture. The skid resistance is reported as friction measurements at these speeds and by comparison with the minimum friction level.

This European Standard describes a method for determining the slip/skid resistance of a surface using a device which remains stationary at the test location. The slip/skid resistance is measured by means of a slider mounted at the end of a pendulum arm.
The method provides a measure of the slip/skid resistance properties of a surface either in the field or in the laboratory.
This method measures the slip/skid resistance of a small area of a surface (approximately 0,01 m2). This should be considered when deciding its applicability to a surface which may have non-homogeneous surface characteristics, e.g. containing ridges or grooves, or is rough textured (exceeding 1,2 mm patch test).
NOTE As the results from this test are taken at one small location, the results cannot be compared with results from devices e.g. mobile devices, that measure the slip/skid resistance over a long length of a surface.

This European Standard specifies a method for determining the average depth of pavement surface
macrotexture by careful application of a known volume of material on the surface and subsequent
measurement of the total area covered. The technique is designed to provide an average depth value of only
the pavement macrotexture and is considered insensitive to pavement microtexture characteristics.
This test method is suitable for field tests to determine the average macrotexture depth of a pavement
surface. When used in conjunction with other physical tests, the macrotexture depth values derived from this
test method can be used to determine the pavement skid resistance capability, noise characteristics and the
suitability of paving materials or finishing techniques. When used with other tests, care should be taken that all
tests are applied at the same location.

This method defines a process for comparing the friction results from a number of devices.
By combining together the friction and texture from individual measuring devices, it allows skid resistance determined by different dynamic methods to be expressed on a common scale, namely the Skid Resistance Index (SRI).
As its precision has not been determined, the method should not be used in specifications for surface materials.
Friction is essential for a safe grip between vehicle and surface. Surfaces can be in different conditions and of different types, which can lead to varying friction. Another important factor is the climate and weather conditions that indeed affect the friction, in most cases for the worse. This standard excludes surfaces when they are in winter road condition. It also excludes road marking surfaces.

This Technical Specification describes a method for determining the wet road skid resistance of a surface by measuring the LFCRNL using the Road Analyser and Recorder of Norsemeter (ROAR).
In addition to the friction measurement also measurements of pavement texture can be performed.
The method provides friction coefficient measurements of pavements by using a hydraulically braked test wheel at a pre set slip ratio, which can be fixed from 5 % to 95 %. Default value for the Netherlands is 86 %.
The standard test tyre is dragged over a pre wetted pavement under controlled load and speed conditions while its running direction is parallel to the direction of motion and perpendicular to the pavement.
To determine the macro texture of the pavement a laser system is used. This system is placed in front of the towing vehicle in order to measure the macro texture on dry pavements and on the same path as the skid resistance measurement is done. The standard for this measurement and the used measuring device are well described in standards EN ISO 13473-1 and ISO 13473-2.

This Technical Specification describes a method for determining the skid resistance of a paved surface by measurement of the longitudinal friction coefficient LFCS. This Technical specification covers the operation of the Road Surface Tester of arsenal research (RoadSTAR).
The method "RoadSTAR" provides a measure of the skid resistance properties of a bound surface by measurement of the longitudinal friction coefficient using a continuous reading car sized braked wheel fixed slip device.
The method "RoadSTAR" provides skid resistance measurements of pavements by using the modified Stuttgart skiddometer (Stuttgarter Reibungsmesser). RoadSTAR utilizes a measurement representing the steady-state friction on a braked test wheel at a slip ratio of 82 % (for standard conditions), 37,5 %, 50 %, 75 % (for comparison measurements), with locked wheel or under ABS - braking conditions (for research measurements). The test wheel is dragged over a pre wetted pavement surface under controlled load and speed conditions while the test tyre is parallel to the direction of motion and perpendicular to the pavement.
NOTE Three different slip ratios are retained in order to use the same slip speed for the three different nominal testing speeds of 40 km/h, 60 km/h and 80 km/h for comparison measurements. The common slip speed is chosen equal to 30 km/h:
- for a testing speed of 40 km/h it is necessary to apply a slip ratio of 75 %,
- for a testing speed of 60 km/h it is necessary to apply a slip ratio of 50 %,
- for a testing speed of 80 km/h it is necessary to apply a slip ratio of 37,5 %.
A machine conforming to the general characteristics of the RoadSTAR and the specific provisions of this Technical Specification should be used for the tests.
In addition to friction measurements, to estimate the macro texture of the pavement surface, a laser system is used. (....)

This Technical Specification describes a method for determining the wet-road skid resistance of a surface by measurement of the sideway-force coefficient SFCD.
The method provides a measure of the wet-road skid resistance properties of a bound surface by measurement of sideway-force coefficient at a controlled speed.
This Technical Specification covers the operation of the sideway-force Coefficient Machine (SKM) developed in Germany.
The SKM skid resistance measurement technique determines the sideway-force acting on a particular, angled wheel.
NOTE Because wet pavement surfaces exhibit especially large differences in adhesion and constitute an almost exclusive environment in which the adhesion between tyre and pavement can drop to critically low levels, the test pavement is wetted in the region of the test wheel line during measurements.
The SKM measurement technique has been developed for Network-wide measurements of skid resistance during road monitoring and assessment of pavement surfaces on German federal motorways and highways. It is also applicable to skid resistance measurements for road construction contracts.
The skid resistance of a pavement is determined by friction measurements and measurements of pavement texture. Where measurement of pavement texture is required the standard for this measurement and the device is described in EN ISO 13473-1.
