European foreword
This document (EN 12274-5:2018) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2018, and conflicting national standards shall
be withdrawn at the latest by September 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12274-5:2003.
Compared with EN 12274-5:2003, the following changes have been made:
a) In 6.1 the humidity is reduced from 100 % to 60 %;
b) In 6.2 the Abrasion machine is defined in terms of rotating speed and force applied.
This European Standard is one of a series of standards as listed below:
— EN 12274-1, Slurry surfacing — Test methods — Part 1: Sampling of slurry surfacing mixture;
— EN 12274-2, Slurry surfacing — Test methods — Part 2: Determination of residual binder content
including preparation of samples;
— EN 12274-3, Slurry surfacing — Test methods — Part 3: Consistency;
— EN 12274-4, Slurry surfacing — Test methods — Part 4: Determination of cohesion of the mix;

1 Scope
This European Standard specifies a test method for the design of slurry surfacing mixture based on the
determination of the minimum binder content of the mixture and the resistance to wear under wet track
abrasion conditions for the purpose to support the mixture design.
This test can be used for quality control purposes.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN 1097-5, Tests for mechanical and physical properties of aggregates - Part 5: Determination of the water
content by drying in a ventilated oven
ISO 48, Rubber, vulcanized or thermoplastic — Determination of hardness (hardness between 10 IRHD and
100 IRHD)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
set
end of the non-reversible process when the emulsion coalescence takes place
Note 1 to entry: The coalescence of an emulsion is the non-reversible phase starting from the beginning of the
breaking of the emulsion to the total setting when the bitumen emulsion reverts to bitumen in presence of a mineral.
Note 2 to entry: After the set of a slurry surfacing: it is not possible to stir the mixture; free emulsion during
washing with water cannot be observed and an absorbent paper is not stained when pressed slightly onto the
surface of the slurry surfacing.
3.2
set time
time elapsed between placing a slurry surfacing and its setting
3.3
quick setting slurry surfacing
slurry with a set time less than or equal to 30 min
3.4
slow setting slurry surfacing
slurry with a set time more than 30 min
4 Principle
The samples are tested under water, after which the mass-loss by abrasion is measured.
The test consists of an abrasive action operated by means of a hard rubber cylinder which exerts a
planetary side gear rubbing pressure, applied for 5 min, on the surface of a test sample of slurry
previously prepared, cured in an oven, and moistened by immersion.
