FIELD: construction.

SUBSTANCE: radar absorbent asphalt-concrete mixture including a bituminous binder, a stabilizing additive, a filler - crushed stone of a various fractional composition, and a fine filler, with using a radar absorbent material, where crushed gabbro-diabase stone and nickel slag and/or copper slag in the form of sand and/or microspheres obtained by a plasma technology, are used as a radar absorbent material at the next component ratio, wt %: said crushed stone 5-70, bituminous binder 5-18, said nickel slag and/or copper slag 8-80, a stabilizing additive 6-16, other filler 2-18. The radar absorbent asphalt-concrete road covering is made multi-layered, where the bottom layer is made from the above mixture, and the upper strengthening layer is made of a mixture containing a binder - an epoxy composition, nickel slag and/or copper slag in the form of sand and/or microspheres made by plasma technology, a pigment and another filler at the following component ratio, wt %: epoxy composition 10-40, said nickel slag and/or copper slag 10-70, pigment 0 or 1-10, another filler 0 or 1-12. The invention is developed in the dependent claim of the formula.

EFFECT: improved operational properties and extended application range.
