Based on the literary sources analysis, the requirements to composite materials ideal structure were formulated. The ideal compositional materials structure must consist of fine – dispersed mineral part fraction which particles are bound by thinnest bitumen films, according to the P.A. Rebinder`s physical – chemical mechanics theory. There was shown how asphalt concrete`s formula and structure influence the road surface operational characteristics. The active role of mineral powder in asphalt concrete structure forming was stated. The mechanism of structuring effect of a binder in composite and the way it influences the material`s properties was shown. The conversion of bitumen in material structure into thinnest adsorption layers could radically affect the asphalt concrete`s properties. It was stated that standard asphalt concrete mixture compositions do not meet the ideal structure requirements and that bitumen – mineral materials have great potential.
