Zusammenfassung:	The invention relates to a bitumen mixture and to a composition containing said mixture used for hydroinsulations. The bitumen mixture consists of natural bitumen, paraffinic bitumen and road bitumen and is prepared by mixing the components at 150...220°C. According to the invention, the bituminous composition comprises a bitumen mixture and polymers selected from styrene-butadiene rubber, isotactic polypropylene, atactic polypropylene and low density polyethylene and calcium carbonate. Invenţia se referă la un amestec de bitumuri şi la o compoziţie care conţine acest amestec, utilizată pentru hidroizolaţii. Amestecul de bitumuri este constituit din bitum natural, bitum parafinos şi bitum rutier, şi se obţine prin amestecarea componentelor la 150...220°C. Compoziţia bituminoasă conform invenţiei conţine amestec de bitumuri cu polimeri aleşi dintre cauciuc stiren-butadienic, polipropilenă izotactică, polipropilenă atactică şi polietilenă de joasă densitate, şi carbonat de calciu.
