93.080.20 Road construction materials
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.
