FIELD: construction.
SUBSTANCE: invention relates to a bitumen-rubber mastic, containing the following components: road bitumen BND 60/90, rubber crumbs and plasticising additive made of building lime and mineral powder, differing by the fact that additionally it contains a polymer additive from rubber thermoplastic elastomer RTEP at the following ratio of components, wt %: bitumen BND 60/90 - 68-78; rubber crumbs - 9-13; rubber thermoplastic elastomer RTEP 5-7; plasticising additive at the ratio of building lime - mineral powder making 3:7 8-12.
EFFECT: production of mastic with improved physical-chemical parameters, reduced brittleness temperature, increased elasticity and tensile strength.
