Organic composite binder improving the physical and mechanical properties of low-strength stone materials

Based on the results of research and practical tests, the authors have developed a composition and proposed a technology for preparing an organic composite binder capable of deep penetration into pores of low-strength stone material with formation of a hydrophobic well-retained layer on its surface, which provides improvement of the main strength characteristics of the stone. Results of experimental studies are presented, optimal concentration of OCB and minimum processing time are determined. Practical recommendations are given for using the obtained strengthened material, which can act as a full-fledged independent working layer of road structure, as well as a component of asphalt concrete and cement concrete mixtures.
