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.
