test site.
prEN 1824:2008 (E)
4 Test sites and conditions
4.1 General
Test sites shall be arranged at suitable locations in accordance with 4.2 to 4.5. The test results may depend on test
field location, climate, road surface and traffic which shall be described according to clauses 4.2 to 4.6
4.2 Test sites characteristics and location
The test site shall be located in an area which belongs to one of the climatic classes defined in 4.3.
The test site shall consist of a field, where the road marking materials are to be applied, with extra space at both
ends. The roads used for test sites should be straight and flat and without junctions, substantial obstacles to
daylight, sources of frequent dirt (quarries, field exits, etc.) or tracked vehicles.
NOTE It is desirable to have additional areas at the roadsides in order to allow safe working conditions and convenient
operation of application with road marking equipment.
The percentage of heavy vehicles on the test site shall be 10% to 25% of all vehicles.
The location of the test site shall be indicated in the test report.
4.3 Climatic conditions and classes
Climatic classes (see table 1) are defined according to the Köppen classification and the use of winter
maintenance.
Köppen classification shall be determined according to Annex A.
Winter maintenance is defined by the number of of times that snowplough have operated on the test field during
the road trials. Winter maintenance is applicable if this number is equal to or greater than 20 and shall be
considered only for the Köppen zone Cfb.

NOTE The influence or not of climate on the results of road trials has not yet been demonstrated.
prEN 1824:2008 (E)
4.4 Road surface conditions and classes
Road trials shall be carried out on asphaltic road surfaces of an age of 1 year or more, which are in good condition
and not in need of repair for the duration of the road trials and are not damaged by the presence of wheel tracks,
fissures, cracks or similar. Highly porous surfaces shall be avoided.
NOTE 1 Road trials on cement concrete surfaces do not give repeatable results because of on-going chemical reactions.
NOTE 2 Road trials on highly porous surfaces do not give comparable results due to the draining properties.
At the commencement of a road trial, a road surface report of the road trial shall be available. The test surface
report shall include a general description of the road surface and an account of the texture depth (MTD : mean
texture depth), determined in accordance with EN 13036-1 :”Measurements of pavement surface macrotexture
depth using volumetric patch technique”
The MTD shall be measured at several locations on the test field. The number of measurements depends on the
test field length. Measurements shall be carried out, at least, at three transversal locations and repeated every 30m
on the test field. The transversal measurements locations are in the centre of the carriageway, near the right and
left edge line.
The averaged mean texture depth is derived from these measurements. The standard deviation shall be less than
0,15 mm.
NOTE 3 The averaged texture depth may also be directly determined in accordance with EN ISO 13473-1 “Characterization
of pavement texture by use of surface profiles – Part 1 – Determination of Mean Profile Depth”. Depending to the averaged
measured texture depth, the test field roughness is described in term of roughness class according to table 2.
Table 2 - Test field roughness classes
Roughness class Averaged measured texture depth
RG1 ≤ 0,60 mm
RG2 >0,60 mm and ≤ 0,90 mm
RG3 >0,90 mm and ≤ 1,20 mm
RG4 >1,20 mm
NOTE 4 The texture depth has an influence on the result of road trials, at least for materials applied in thin layers.
4.5 4.5 Roll-over classes
The volume of traffic shall be such as to ensure that one or more measurement areas with the desired roll-over
class can be selected (see 7.2).
At the termination of a road trial, a traffic report for the duration of the road trial should be made available. The
traffic report shall include the roll-over classes according to Table 3, determined on the measurement area(s) in
accordance with annex B.
prEN 1824:2008 (E)
Table 3 – Roll-over classes
Roll-over class Number of wheel passages
T0
≤ 50 000
T1 Between 50 000 and 60 000
T2
100 000 ± 20 %
P0
≤ 50 000
P1 Between 50 000 and 60 000
P2 100 000 ± 20 %
P3
200 000 ± 20 %
P4
500 000 ± 20 %
P5 1 000 000 ± 20 %
P5.5
1 500 000 ± 10 %
P6
2 000 000 ± 10 %
NOTE The roll-over classes T0, T1 and T2 are for materials intended for temporary road markings, while the roll-
over classes P0, to P6 are for materials intended for permanent road markings.
The traffic report should further include the percentage of heavy vehicles together with an indication of the counting
method used.
A vehicle is considered a heavy vehicle if its maximum gross mass is above 7500 kg.
4.6 Studded tyres classes
For road trial sites where studded tyres are used to a significant degree, this shall be indicated on the test report.
NOTE From general experience, such traffic conditions can be relevant to the erosion of road markings.
5 Organization of road trials
5.1 Duration
A road trial shall include at least one full climatic cycle of one year for materials intended for permanent
road marking and up to 6 months for materials intended for temporary road marking.
In some cases test markings may fall below the performance requirements of the road authority. In these
cases, it may be necessary for the markings to be removed.
5.2 Transverse and longitudinal application patterns
5.2.1 General
Road marking materials shall be applied in patterns of lines either transverse or longitudinal to the road.
When a long (more than 30 cm) measurement area is necessary, the transverse pattern cannot be used.
When both the transverse and longitudinal patterns are used on the same test site, they shall be used on separate
parts of that test site.
5.2.2 Transverse pattern
At least three lines shall be applied for each road marking material. The distance between two adjacent lines
should be at least 0,35 m and the width at least 0,15 m as shown in figure 1. The application could be done across
one or two lanes.
NOTE Lines of the same material need not be adjacent.
