FIELD: chemistry.
SUBSTANCE: invention relates to road construction and can be used in road pavement in all climatic regions. The invention relates to a rubber stone-mastic asphalt mix for road construction which contains road bitumen, crushed stone, sand from grinding screenings, mineral powder and a stabilising additive. The mineral powder used is rubber crumbs with size of up to 1 mm and the stabilising additive used is low-density secondary linear polyethylene, with the following ratio of components in wt %: crushed stone 60-84; road bitumen 5.5-7.5; rubber crumbs 1.0-1.8; low-density secondary linear polyethylene 0.2-0.8; sand from grinding screenings - the rest.
EFFECT: improved physical and mechanical characteristics of the stone-mastic asphalt mix.
