Abstract: Currently for many construction industries promising becomes the creation of waterproofing materials on the basis of integrated management natural oily raw material, as well as improvement of traditional bituminous materials with polymeric and Surface-Active Additives (SAA). Choice of material depends on the working conditions of a hydraulic installation, categories of reliability construction its structures, the availability of local building materials, method of work and technical and economic indices of construction. The study presents the results of studies of hydrotechnical properties of mastics. The analysis of the results of laboratory tests allowed for the optimization of its content in bitumen. It has been demonstrated that the properties of mastics based on petroleum bitumen rocks studied by the authors of the study has a significant impact on physical characteristics of bitumen.
