Introduction

A particular category of road marking materials, used for horizontal signalisation, are

preformed road markings, manufactured products in the form of sheets or on rolls, ready for

use on the road. They can be applied by means of adhesives, pressure or heat, with or without

the use of a primer. Preformed road marking materials can be linear, in pieces of a certain

length or in rolls. They can also be cut out in the form of symbols or signs or parts of them,

making it possible to assemble them on the road to achieve the desired shape.

Preformed road marking materials can be designed for use as permanent or temporary road

markings. Temporary road markings, as covered in Annex A, are applied with a view for later

removal and therefore the specific property of “removability” can be required.

Preformed road marking products are defined as Tape, preformed Cold Plastic road marking

or preformed Thermoplastic road marking.

These type of products are fully finished during manufacturing and do not change significantly

their properties during application. They are completely covered by this standard.

Release of dangerous substances

National regulations on dangerous substances may require verification and declaration on

release, and sometimes content, when construction products covered by this standard are

placed on those markets.

In the absence of European harmonized test methods, verification and declaration on

release/content should be done taking into account national provisions in the place of use.

NOTE An informative database covering European and national provisions on dangerous substances is

available at the Construction website on EUROPA accessed through: http://ec.europa.eu/growth/tools-

databases/cp-ds_en.

3.1
preformed road marking

factory produced road marking system (or product), in sheet or roll form, capable of being

applied to the substrate with adhesive, primer, pressure, heat or a combination of these. These

type of products are fully finished during manufacturing and do not change significantly their

properties during application

Note 1 to entry: Additional materials to those described in 3.1.1 to 3.1.3 can include, if recommended

by the manufacturer, primers which are liquid products which may contain solids and liquid additives

suspended in an organic solvent or in water. The solids comprise inorganic and/or organic fillers,

pigments and additives. The content of volatile organic solvents is not limited. Primers are used to

precoat road surfaces before the road marking system is applied. They improve the adhesion of the road

marking and protect against disintegration, discolouring, etc. caused by incompatible compounds in the

road surface.
3.1.1
tape

preformed multilayer road marking, capable of adapting itself to the texture of the substrate,

which may be precoated with pressure-sensitive adhesive, capable of being stuck to the

substrate without heating the material, while the photometric, colorimetric and skid

resistance characteristics are not significantly modified during application
3.1.2
preformed cold plastic road marking

preformed road marking made of cold plastic marking material as defined in prEN 1871:2018,

applied to the substrate by means of an adhesive, while the photometric, colorimetric and skid

resistance characteristics are not significantly modified during application
3.1.3
preformed thermoplastic road marking

“pre-beaded” preformed road marking made of thermoplastic marking material as defined in

prEN 1871:2018, applied to the substrate by heating the material until adhesion to the

pavement and without the addition of any retroreflective and/or anti-skid drop-on materials

during application to the road
3.2
removability

characteristic of a temporary preformed road marking capable of being removed, intact or in

large pieces, without leaving permanent marks that could confuse the road user during

different weather conditions
3.3

3.5
type I road marking
road marking that does not necessarily have special properties
3.6
type II road marking

road marking with special properties intended to enhance the retroreflection in wet or rainy

conditions
4 Product Characteristics
4.1 General

The performance is meant as characteristic of the material as fully finished product. The

performance can be assessed on samples in a laboratory, but also on samples applied on the

road or wear simulator. The performance shall be measured after removing any surface

coating used to protect the surface of the preformed road marking during roll-up and

transport, following the instructions of the manufacturer.
4.2 Essential Characteristics
4.2.1 Day-time Visibility (Reflection in daylight or under road lighting)

Reflection in daylight or under road lighting is measured either by the luminance coefficient

−2 −1

under diffuse illumination Qd in the direction of traffic and expressed in mcd⋅m ⋅lx ; or by

the luminance factor β.

a. When luminance coefficient under diffuse illumination Qd is measured, the preformed

road marking material is tested in accordance with 5.2.2 a), test results shall be expressed

by means of classes Q0 to Q5 of EN 1436:2018, Table 1.

b. When luminance factor β is measured, the preformed road marking material is tested in

accordance with 5.2.2 b), test results shall be expressed by means of classes B0 to B5 of

EN 1436:2018, Table 2.

4.2.2 Night-time Visibility (Retroreflection under vehicle headlamp illumination)

Retroreflection under vehicle headlamp illumination represents the brightness of a road

marking as seen by the vehicle driver under the illumination by the vehicle’s own headlamp.

−2 −1

The result is expressed by the coefficient of retroreflected luminance R in mcd·m ·lx .

The coefficient of retroreflected luminance, measured on dry conditions, changes during

wetness or during rain. Retroreflected luminance during wetness or during rain only applies

for type II road markings.

a. When preformed road marking material is tested on dry conditions, in accordance with

5.2.3 a), test results shall be expressed by means of classes R0 to R5 of EN 1436:2018,

Table 3.

b. When preformed road marking material is tested during wetness in accordance with 5.2.3

b), test results shall be expressed by means of classes RW0 to RW6 of EN 1436:2018,

Table 4 (only for type II road marking products).
---------------------- Page: 11 ----------------------
oSIST prEN 1790:2020
prEN 1790:2019 (E)

c. When preformed road marking material is tested during rain in accordance with 5.2.3 c),

test results shall be expressed by means of classes RR0 to RR6 of EN 1436:2018, Table 5

(only for type II road marking products).
4.2.3 Day-time Visibility (Chromaticity coordinates)

Chromaticity in daylight shall be defined by means of (x,y) chromaticity coordinates.

When a white preformed road marking is tested in accordance with 5.2.4, test results shall be

expressed by means of colour regions defined by the corner points given in EN 1436:2018,

Table 6 for white road markings.

When a yellow preformed road marking is tested in accordance with 5.2.4, test results shall be

expressed by means of colour regions defined by the corner points given in EN 1436:2018,

Table 6 for yellow road markings.
4.2.4 Night-time Visibility (Chromaticity coordinates)

Chromaticity in nighttime for retroreflected light shall be defined by means of (x,y)

chromaticity coordinates.

When a dry yellow preformed road marking is tested in accordance with 5.2.5, test results

shall be expressed by means of colour regions defined by the corner points given in

EN 1436:2018, Table 7 for yellow road markings.
4.2.5 Skid resistance SRT value (only for non-structured road marking products)

Skid resistance represents the energy loss caused by the friction of a rubber slider over a

specified length of a road marking surface in wet conditions. The result is expressed in SRT

(Skid Resistance Tester) units.

Measured according to 5.2.6, test results shall be expressed by means of classes S0 to S5 of

EN 1436:2018, Table 8.

This test is valid for flat road markings and road markings with low degree of texture. Road

markings with high degree of texture or structured markings may not be suitable for

measurement of skid resistance by this method, see definitions in EN 1436:2018, 4.5.

4.3 Durability
4.3.1 General

Durability represents the capability of the preformed road marking material to retain the

performance of the essential characteristics declared by the manufacturer after being

submitted to road trials and/or wear simulator.

This European Standard considers two possible methods of verification and/or assessment of

durability taking into account that some Member States have national regulations based on

one of them and considering that state of the art on this matter does not allow to define a single

and unified test method.

The information corresponding to the durability method road trials or wear simulator shall

include the specific test conditions applicable to the test.
