Bitumen concrete construction and technical properties improvement when used as refuse finely-fragmented layer inorganic material formed in production of ceramic granite, ceramic construction material, is conditioned by its phase composition and structure. The set of physicochemical studies has established that the high physical and technical properties of ceramic granite are associated with its microstructure, which presents glassceramic composite consisting of amorphous glass phase permeated with mullite crystals and silica-containing phases of quartz and cristobalite, that provides low material porosity. The density of natural granite containing only β-quartz in an amount of about 35% with its density and the density of other minerals in the granite, in particular field spars, is 2.6… 2.7 g/cm3. The density of ceramic granite decreases due to less dense β-cristobalite, but at the same time its porosity decreases due to glass crystal structure. Use of non-porous refuses of ceramic granite as finely-fragmented inorganic material reduces amount of bitumen in bitumen concrete mixture, increases water resistance, compressive strength, shear resistance of bitumen concrete, which can increase service life of road surface.

“…It has been established that for obtaining asphalt concrete with improved properties, the optimal porcelain stoneware fraction is 0-5 mm. The high density of porcelain stoneware helps to reduce the amount of bitumen by 15 ... 20% [8,9].…”

The possibility of using waste porcelain stoneware - a high-strength non-porous, dense material as a finely crushed mineral part of asphalt concrete with 0-5 mm fraction has been established. The adhesive additive Bitaden content was revealed, that intensifies porcelain stoneware interaction with bitumen due to the additional hydrogen bonds formation, the particles’ contact plane activation with the action of van der Waals forces. The conditions for obtaining asphalt concrete mixtures of type B, grade 1 and G, grade 2 of the optimal grain composition with a reduced content of BND 60/90 bitumen have been developed. Physical and mechanical properties are characterized by an increase in the water resistance of asphalt concrete samples based on porcelain stoneware, compressive strength and shear resistance.
