21、duction The adhesion between binder and chippings is the basis of successful surface dressing. lt is important that this bond can be obtained, initially, at the moment of construction and be ensured in cool conditions when the adhesivity problems become dominant binder with damp or dry and dusty chi
22、ppings. A knowledge of adhesivity enables the choice of a binder and aggregate type for minimum risk, especially for early and late season work. 1 Scope This European Standard specifies the measurement of the binder aggregate adhesivity, and the influence of adhesion agents or interfacial dopes an a
23、dhesion characteristics as an aid to design binder aggregate systems for surface dressing. lt is not intended that this method is used on site for quality control. This European Standard specifies methods of measurement of: the mechanical adhesion of the binder to the surface of the aggregate; the a
24、ctive 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 vari
