Process for preparing bituminous product and aggregate mixture comprises mixing the product with the aggregate containing at least an additive (A), where: the mixing is carried out with temperature granular fractions, for producing a coating at a temperature of 60-200, preferably 100-200[deg] C; the temperature for producing aggregate and bituminous product mixture in production outlet is lowered up to 50?C; and the temperature of the aggregates and bituminous product mixture during spreading is lowered to 5-50[deg] C. Process for preparing bituminous product and aggregate mixture comprises mixing the product with the aggregate containing at least an additive of formula ((R-O-(CH 2CH(CH 3)O) a-(CH 2CH 2O) b) cP(=O)-OH d) (A), where: the mixing is carried out with temperature granular fractions, for producing a coating at a temperature of 60-200, preferably 100-200[deg] C; the temperature for producing aggregate and bituminous product mixture in production outlet is lowered up to 50?C; the temperature of the aggregates and bituminous product mixture during spreading is lowered to 5-50[deg] C; the temperature of the aggregate and bituminous product mixture in core of the carpet at the beginning of compaction is lowered to 10-50[deg] C; and the dosage of (A) measured to the ton of bituminous product is 0.3-20 kg. P : phosphorus atom; either c : 1-2; or c+d : 3; a : 0-80; b : 0-10; and R : 6-30C hydrocarbon chain (optionally saturated and optionally contain an aromatic core, structure of polypropylene glycol parts and polyethylene glycol optionally statistical or in blocks, the order of blocks is not restricted).
