Abstract
In the temperature range –10–30°С the influence of thermo-oxidative aging, frequency and deformation on the interfacial interaction according to the parameters K–B–G* and К–В–δ in asphalt mastics and modified mastics based on bitumen grade BND 60/90 has been investigated. The filler was introduced into bitumen in the ratio of 1/1 by weight. Active powder of discretely devulcanized rubber (APDDR) as a modifier was introduced in the ratio bitumen/APDDR = 87.5/12.5 by weight. It is shown that the modification of APDDR provides a greater thickness of adsorbed layer on the surface of filler particles under various conditions of external influences compared to mastic, and this thickness depends on the sequence of introduction of filler and APDDR.
期刊介绍:
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
