Bituminous suspension of solid emulsifier

Abstract

The technical result achieved as a result of solving the problem is to increase the degree of dispersion and homogeneity of the bitumen composition while maintaining the viscous aggregate state of the bitumen in the bitumen composition during its storage and transportation. The technical result is achieved by the fact that in the bitumen composition in the form of a suspension comprising a dispersed aqueous medium and a dispersed solid phase distributed therein, the dispersed solid phase consists of mineral powder particles and particles from bitumen droplets in a viscous aggregate state stabilized by a shell of mineral powder particles coated with a structured (oriented) layer of water, at the following ratio of the suspension components, %: particles from bitumen droplets in a viscous aggregate state, coated with mineral powder particles – 30-45 %; mineral powder particles 30-50 %; technical water-15-30 %. As a substance of mineral powder used, for example, carbonate rock or phosphogypsum dihydrate in the molecular state (from the reactor nezabitovskiy). As a solid dispersion phase, hydrophilic mineral powder is used, technogenic by-products of industrial production (crushed basic metallurgical slags, fly ash, dust-entrainment of cement plants, etc.) can be used as mineral powders.
