Surface dressing - Test methods - Part 3: Determination of binder aggregate adhesivity by the Vialit plate shock test method; German and English version prEN 12272-3:2024

Abstract

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.
