Abstract: The automated test facility for definition of samples’ shift- resistance of a road covering by bitumen materials for conditions of operation of motorways of Siberia is created. The essence of a test method consists in an estimation of accumulation of deformation of the asphalt-concrete’s sample at the set quantity of passes under the influence of loaded обрезиненного wheels of the certain size at back and forth motion and at settlement temperature. It is shown, that principal causes of premature destruction of coverings are physicomechanical properties of a large filler. Classification of the form of grains of a large filler is offered.

Key words: asphalt-concrete the large filler the automated test facility
