Theoretical and experimental studies carried out by scientists from the Federal State Budgetary Educational Institution of Higher Education “DONNACEA” have shown that the most effective compositions for the construction of structural layers of asphalt concrete road pavements are the production and use of complex-modified asphalt concrete mixtures of type II macrostructure (type B, crushed stone mastic) with a complex-modified microstructure, namely, the production of a bitumen-polymer binder by modifying petroleum road bitumen with butadiene methyl styrene rubber SKMS-30 (2-3% by weight) and technical sulfur (25-30% by weight) with surface activation of mineral powder with butadiene methyl styrene rubber (0.5-0.7% by weight), and the introduction of chrysotile asbestos fibers of the A-6K-30 brand into the microstructure. The annual economic effect from the introduction of a complex-modified asphalt concrete mixture at the asphalt concrete plant of OOO DONSPETSPROM of the Donetsk People's Republic is 202,262 rubles, the payback period for additional costs is 0.1 years.
