摘要：This paper provides the results of the studies of polymer-bitumen sealing compounds for sealing seams and cracks in asphalt con-crete road. The polymers used were waste from Krasnoyarsk factories (rubber-fabric and butyl-rubber crumbs) and Tomsk factories (polyethylene waste and atactic polypropylene). Here we formulate the basic require-ments for sealing compounds applied in the Siberian regions. An experi-ment has been carried out with the use of the planning method, we pre-pared the compounds and determined their basic properties, as well as plot-ted the isolines of the compounds’ properties depending on the proportion-ing of mineral powder and polymer waste. Based on the analysis of the iso-lines and comparing the properties with the requirements, we selected the optimal compositions of the prepared sealing compounds and defined their core indicators. As a result of the research, the mastic based on butyl-rubber crumbs was chosen as the one meeting all the requirements by all the indicators. This paper reflects the results of the test surveys on pouring cracks in the road surface of Krasnoyarsk. The developed sealing com-pound has been adopted in production on the roads of Krasnoyarsk Territo-ry.
