scope:

This European Standard specifies a method for determining the adhesion of a bituminous emulsion coated onto aggregate when immersed in water. The method considers two different aspects of adhesivity, i.e. immediate adhesivity and water effect on binder adhesion. The method may be used with a reference aggregate. In that case, it measures the intrinsic adhesion behaviour of a bituminous emulsion. The method may also be used with a specific aggregate as used on a job site. This revised version (EN 13614:2011) makes a distinction between "immediate" adhesivity and water effect on binder adhesion. Compliance to the adhesivity requirements set by EN 13808 is verified according to the procedure defined for testing water effect on binder adhesion.
