This document specifies a test method for determining the suitability of aggregates and cationic emulsions for slurry surfacings and, where appropriate, the effect of individual additives.
This document applies to slurry surfacings.
NOTE 1   The procedure uses a standard mixture but the method may also be used to assess the effect of variations in the grading and binder content but this use is not part of the standard.
NOTE 2   Additives affecting the breaking behaviour may also be tested under standardised conditions. The test may also be used to study the effect of a particular type of bitumen or emulsifier.

This European Standard specifies methods of assessment of the defects which may occur with a surface dressing. The assessment of the defects evaluates the condition or performance of the surface dressing and, thus, gives an indication on the durability of the surface dressing. This standard is applicable to all surface dressings (roads, airfields and other trafficked areas). The checklist in Annex A (normative) is a preliminary to the test method.

This European Standard applies to the measurement of the binder-aggregate systems for surface dressing. This European Standard specifies methods of measurement of: the mechanical adhesion of the binder to the surface of the aggregate, - the active adhesivity of the binder the the chippings, - the improvement of the mechanical adhesion and active adhesivity by adding an adhesion agent either into the mass of the binder or by spraying the interface between binder and chippings, - the wetting temperature fo the binder to the aggregate, - the variation of adhesivity below the fragility temperature.

This European Standard specifies test methods for determining the rates of spread and accuracy of spread of binder and chippings of a surface dressing on a section of road at a given time. It is also applicable to surface dressings on airfields and other trafficked areas.
The test methods are used on site to check the ability of binder sprayers and chipping spreaders to meet the intended rates of spread and tolerances and coefficients of variation.
The test methods for measuring the rates of spread and accuracy of spread of binders and chippings are not applicable to combined chipping-binder spreaders.

This document specifies, for anhydrous bituminous binder (cut-back and fluxed bituminous binders), the measurement of the binder aggregate adhesivity and the influence of adhesion agents or interfacial dopes and adhesion characteristics as an aid to design binder aggregate systems for surface dressing.
This document specifies methods of measurement of:
-   the mechanical adhesion of the binder to the surface of the aggregate;
-   the active adhesivity of the binder to the chippings;
-   the improvement of the mechanical adhesion and active adhesivity by adding an adhesion agent either into the mass of the binder or by spraying the interface between binder and chippings;
-   the wetting temperature of the binder to the aggregate;
-   the variation of adhesivity below the fragility temperature.
The wetting capacity of the binder affects the adhesivity properties. With the presence of water, the wetting capacity of bitumen emulsion is naturally high. Even if mechanical adhesion and active adhesivity test methods are mainly dedicated to anhydrous bituminous binders (cut-back and fluxed bituminous binders), these measurements can also be practiced with bitumen emulsion with a personalized interpretation of the results that depends on the design of the binder aggregate system. For bitumen emulsion, the adhesivity is conventionally measured through the water immersion test (EN 13614).
This test method is applicable for:
-   bituminous binders used for surface dressings (e.g. conventional or polymer modified binders; mainly anhydrous bituminous binders such as cut-back and fluxed bituminous binders and bitumen emulsions);
-   all the following aggregates sizes that can be used for surface dressings:
-   set 1: 2/5 mm, 5/8 mm, 8/11 mm and 11/16 mm; and
-   set 2: 2/4 mm, 2/6 mm, 4/6 mm, 4/8 mm, 6/10 mm, 6/12 mm and 10/14 mm.
It is not intended that this method be used on site for quality control.
NOTE   Further information concerning the purpose of the test can be found in Annex D.
WARNING - The use of this document can involve hazardous operations. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use.

This document specifies test methods for determining the rates of spread and accuracy of spread of binder and chippings of a surface dressing on a section of road at a given time.
This test method can also be used for determining the rate of spread and accuracy of spread of sprayed bituminous emulsions e.g. when used as bond coats or asphalt preservation systems. The performance categories for binder rate of spread and accuracy of spread in EN 12271 do not apply to bond coats and tack coats.
The test methods are used on site to check the ability of binder sprayers and chipping spreaders to meet the intended rates of spread and tolerances and coefficients of variation.
The test methods can be used to fulfil the Factory Production Control requirements:
-   equipment calibration (EN 12271 - Annex B - Table B2);
-   production inspection (EN 12271 - Annex B - Table B6).
The calibration of binder and chipping spreaders requires strict application of the procedures described in this document.
Using these methods for inspections during production (FPC), allows certain changes to these methods due to the specificity of certain sites and materials used (e.g. combined chipping-binder spreaders). In this case, the changes are documented in the Factory Production Control and identified in the test reports.
Other test methods used to check the rate of spread and accuracy of spread of binder, such as the static spray bar bench test for sprayers, are not covered by this document, although the test methods in this document can be used for this purpose.

This document describes the performance requirements and control procedures for the
installation of slurry surfacing on airfields as a product for the surface treatment of areas
trafficked by Aircraft (e.g. runways on „low” trafficked airfields, aprons and taxiways).
NOTE The installation of slurry surfacing on airfields requires experience and skills
from both the Client and the Contractor. The suitability of the product for a particular
airfield application and the capability of the contractor have to be considered carefully in
every case.
This document does not apply to small areas of slurry surfacing that are less than 500 m2
which are not contiguous (for example minor repairs).
