RESEARCH OF MINERAL FILLER INFLUENCE ON THE PROPERTIES OF ROAD-CONSTRUCTION BITUMEN

In the article the technology of obtaining rubber modified bitumen using highly dispersed crumb rubber waste is developed, the properties of the obtained compositions are researched. For the production of asphalt concrete mixture, road bitumen and mineral filler have been modified. Asphalt concrete pavement allows for a twofold reduction of noise and vibration, lowers the possibility for the formation of ice crust and improves the adherence. Thus the increase of frost and water resistance of asphalt concrete is achieved.
