FIELD: road repair work.
SUBSTANCE: invention relates to the field of road repair work and can be used when reusing old asphalt concrete. The method of increasing the density and strength of asphalt granule concrete includes fractionation of asphalt granulate, selection of a fraction of up to 40 mm, heating to a temperature of 60-70 °С adding a plasticizing additive Wetfix BE or DAD-TA during heating in an amount of 0.5-0.6% by weight of bitumen.
EFFECT: increasing the speed of the method while simplifying it.
