摘要： The invention relates to bituminous compositions obtained by the incorporation of thermoplastic polymer residues, particularly sterile car waste, containing polyurethane foams and thermoset resins, as well as their preparation process. The process consists of mixing previously ground polymer residues, so as to obtain an average particle size below 10 mm with melted asphalt or bitumen. The mixture is stirred at a temperature between 150.degree. and 300.degree. C., the presence of ground polyurethane foam and thermoset resin particles helping to increase the dissolving rate of the polymers. Preferably addition takes place of a catalyst and/or a reagent aiding a coupling reaction between the polymers and certain constituents of the bitumen or asphalt, which gives the final bituminous mixture improved properties. The bituminous compositions according to the invention can advantageously be used for coating solid materials.
