FIELD: construction.SUBSTANCE: invention relates to road construction, namely to methods of elimination of local depressions on asphalt concrete coating of motor roads. Method of elimination of local depressions on asphalt concrete coating of motor roads includes cleaning of depression, arrangement of granulated asphalt concrete mixture of bitumen and filler into it and formation of local coating. At that, walls and bottom preliminarily cleared local recesses are steeped with flammable liquid and combustible element of corrugated sheet material is placed at bottom, e.g. cardboard, after placing on it, similar to cover, support element of meshy material, for example, polymer fibre or glass fabric, and then on support element granular asphalt mix of bitumen and coarse mineral filler is laid with layer necessary for filling of recesses, and before formation of seal coating on recess is burning corrugated combustible element in it by its ignition from burning combustible fluid on surfaces of recesses and air supply under support element by its delivery with pump.EFFECT: simplified method implementation, reducing of material consumption and labour intensity.1 cl, 1 dwg |
