It has been shown that waterproofing mastics (WM) should have increased indicators of water, wear and heat resistance, adhesion to surfaces, environmental friendliness, durability, etc. The relevance of reducing the prime cost of WM with the simultaneous improvement of their properties, due to the introduction of mineral fillers of natural and technogenic origin, as well as wastes of various industries, in polymer- bitumen compositions . The possibilities of introducing secondary products of the petrochemical and rubber technical industry into the composition of the WM, as well as the possibility of using asbestos, kaolin, montmorillonite, karelite and other fillers are generalized. It has been experimentally proved that the use of polymeric plasticizing and rubber wastes, as well as mineral components in the composition of WM, made it possible to obtain a composition having advantages in strength of adhesion and conventional strength up to 3 times, in water absorption up to 5 times, in relative elongation up to 7.5 times, in comparison with regulatory requirements.
