Resumo
The possibility of utilization of overburden rocks of the Chernovsky brown coal and Baleysko-Taseevsky gold occurrences (Trans-Baikal Region) in the road construction industry is studied. Polymeric additives “Cryogelite” and “StabOL” were chosen as stabilizing additives in the compositions of road-building composites. The initial mineral samples were examined by methods of atomic emission spectrometry with inductively coupled plasma, powder diffraction, and infrared spectroscopy. It was found that the introduction to formulation of composites with use of overburden rocks of 8 wt. % Portland cement and 10 wt. % fly ash, as well as stabilizing additives “Cryogelit” (Chernovskoe occurrence) and “StabOL” (Baleysko-Taseevskoe occurrence), allows to obtain samples with strength grade M40 and frost resistance grade F15. The biotesting method proved that the obtained composites do not have an acute toxic effect on test objects and are safe for the environment and human health.
