Sealing mastics for road surfacing in Siberian regions

Abstract

This paper provides the results of the studies of polymerbitumen sealing compounds for sealing seams and cracks in asphalt concrete 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 requirements for sealing compounds applied in the Siberian regions. An experiment has been carried out with the use of the planning method, we prepared the compounds and determined their basic properties, as well as plotted the isolines of the compounds' properties depending on the proportioning of mineral powder and polymer waste. Based on the analysis of the isolines 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 butylrubber 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 compound has been adopted in production on the roads of Krasnoyarsk Territory.
