Annotation: Improving the properties of asphalt binders under ordinary conditions is achieved through the use of additional expensive surfactants that complicate not only the technology of preparation of asphalt binders, but also increase its cost. The multicomponent system, which is an organomineral powder from sewage sludge, allows to improve the adhesion of bitumen to the surface of mineral grains, improve the quality of asphalt concrete and improve the performance of the preparation of asphalt binder through the participation of surface-active substances and heavy metals in the formation of heterotrophic salts of humid acids, comprehensively -heterotrophic salts, chelate adsorption complexes containing metal in the anionic part of the molecules in the form of a cation capable of dissociation. Thus, the improvement of the properties of the asphalt binder using organomineral powder is ensured by the presence of surfactants in the sewage sludge, and the technology of preparing the asphalt binder is significantly cheaper.
Keywords: surfactants, binder, sewage sludge, organomineral powder, adsorption, surfactants.
