Plasticizing Additive to Road Bitumens Based on High-Sulfur Brown Coal
Using the oxidation desulfurization method, a plasticizing additive for road bitumen was obtained from high-sulfur brown coal. Taking into account the need to maximize the quantity of the plasticizing additive while maintaining quality, constant conditions of the oxidative desulfurization process were selected and the influence of the main variable technological factors on it was investigated. The sample of a plasticizing additive was obtained in near-optimal conditions of the lignite oxidation desulphurization process.
