Essay

Object of research: processes of co-operation bitumen with the surface of mineral materials, stipulating water-resistance of bitumen mineral materials on the road surface. The purpose of research: rise the long term water-resistance of the asphalt concrete for the built of road surface in the conditions of hot and humidity climate by activating of surface of mineral materials by the chloride iron. Methods of research: theoretical, experimental laboratory and model at introduction. Theoretical and practical results: it is possible to produce correlation dependences on the basis of which choice of constituents of asphalt concrete, able to provide its promoted water-resistance in road surface. Novelty: magnitude and character of isotherms of adsorption, correlation dependences, absence of chemical co-operation in the system, efficiency of activating of surface of stone materials by solution of chloric iron Degree of introduction: the developed method has been realized at the device of a 17500 m2 superficial treatment in the site of roads Kharkov - Sherbakovka and Zaporozhia - Mariupol. Sphere of the use: construction and reconstruction of the road surface.
