Manufacturing method for asphalt-and-tar compositions with stabilizer included, characterized in that more than 30 parts per weight of petroleum asphalt and more than 30 parts per weight of coal tar against 100 parts per weight of those materials are joined with each other, and preferably by liquation at temperature of 363-383K, and the bitumic liquid so made is then stabilized by means of a stabilizer in the quantity of 1-60 parts per weight, whereas the stabilizer can include: chelating polymers, chelating oligomers, or aliphatic polymers, whereas it is preferable that the stabilizer is added to the bitumic substances output.
