The analysis of the types of rigid road surfaces, namely cement concrete with a mineral binder and asphalt concrete with an organic binder, was carried out. The comparison of these composite materials according to various physical and mechanical and operational parameters was carried out. The main comparison criteria are: strength, deformability, quality of adhesion of the components of the compositions of asphalt concrete and cement concrete mixtures, as well as the layers of the road structure to each other. As a result of the analysis made, insufficiently studied issues were identified. Increasing the strength and shear resistance of the road structure is one of them. This is facilitated by the introduction of modifying components of various composition and genesis. The composition of the mixture is proposed, in which the mineral component is cement, the organic component is bitumen emulsion, as well as there are inert materials from dense rocks. As a result of tests conducted, a significant increase in the strength of the final composite was revealed. A variant of solving the problem of adhesion of heterogeneous components of composite mixtures, as well as layers of a road structure to each other, is proposed. The introduction of mineral filler into the frame asphalt concrete mixture can increase the strength and shear resistance of the road structure as a whole.
