A research purpose is an increase of roughness of existent travelling and commuter coverages with development of cement mixture of optimal composition and realization of laboratory researches of cement mixture of optimal composition with determination of physicomechanicaland operating properties, development of rational technology of her preparation and conclusion. Research method: analytical-experimental method with usage of mathematical tools by virtue of creation of mathematical models. As a result, the project received a new thin-layer surface of high roughness where the a hard layer placed on non-rigid foundation. This results the im-proved adhesion properties of existing asphalt pavement at any time of year. Based on the general characteristics of these materials is achieved adsorption character of interaction with the formation of adsorption bonds. Consequently, there is a change of the boundary layers viscosity and oriented molecular structure of them. This structure prevents premature detachment of the top layer of the rough surface of the existing pavement and prevents water penetration in existing pavement.
