Mishyk K. Developing repair technology of soft roof covering by liquid and viscous bituminous polymeric compositions

The dissertation is devoted to the development of a new repairing technology of multilayered roofing using special restoring compositions for increasing operational roofing characteristics. The classification of technologies is given taking into account the influence of the types of defects, methods of performing work, as well as the materials used. The main methods of studying the performance characteristics of multilayer roofs are given. Produced a number of studies on the selection some compositions of the repair composition. Experimentally established patterns made it possible to find the optimal ratios of the repair composition to ensure the maximum effect of the developed technology. Each component is assigned a function that aims to improve the properties of an existing carpet. Taking into account the laws obtained and the practice of preparing the known roof mastic, the technology for obtaining the repair composition is presented postoperatively. An algorithm for taking into account factors influencing the choice of a set of technological solutions for repairing soft roofing coatings is presented. A new technology has been developed for repairing soft roofing as a set of organizational and technological parameters for roof repair, indicating the qualifications of contractors, methods and methods for performing work, parameters for preparing a repair composition, and control methods aimed at increasing the time between repairs to ensure a number of coating characteristics. A set of organizational and technological decisions proposed provides longer terms between repairs increasing hydroisolating and waterproofing properties of roofing by saturating the entire thickness of the repaired surfaces with the mentioned above compositions. The technology also enables to eliminate the random errors of roofers and to reduce material consumption. The mixture compositions for repaired surfaces developed in the dissertation improve efficiency of repairing technology. Each component is given the property to improve characteristics of existing roof covering. Due to the experiments it was determined the optimum value of liquid and viscous bituminous polymeric composition to maximize the effect of repair. Keywords: soft roof covering, mixture compositions, organizational and technological decisions, hydroisolating, waterproofing, bituminous polymeric composition.
