Mixed polymer compositions as the basis of the adhesive layer for bitumen tapes

The stability of the surface layers of asphalt concrete (especially at longitudinal and transverse joints of strips laid at different times) can be increased by using bitumen-polymer joining tapes. However, in a number of cases, reliable fastening of the docking tape in an upright position cannot be achieved due to unsatisfactory natural and climatic conditions, creating foci of subsequent destruction. One widely discussed solution is to create an adhesive layer on the side of the connecting bitumen-polymer tape capable of providing the necessary level of adhesion from the moment it is distributed until the end of laying and compaction of a fresh layer of hot asphalt concrete. This study is devoted to the study of two-component compositions based on high-pressure polyethylene and styrene-butadiene thermoplastic. The dispersion medium for this study was residual bitumen from petroleum fractions of Yareg oil, which differs in composition from traditional viscous petroleum bitumen mass produced through oxidation.
