FIELD: chemistry.SUBSTANCE: invention relates to mixture friable anti-icing reagents for road processing. An anti-icing reagent (material) represents a mixture of natural, sieved or milled sandstone, fungicidal additives, salt components in an amount from 2 to 5% of the sandstone weight and water from 3 to 15%. Particles of sandstone superficially freeze to the compacted snow and ice, forming a stable abrasive coating, remaining on the surface after cleaning the fallen snow.EFFECT: invention makes it possible to accelerate the process of the abrasive coating formation, cheapen the technological production process, reduce dusting in production and application.2 cl, 3 ex |
