Thermo-Oxidative Aging of Bitumen, Modified by the Reactivity of the Oligomers, in a Thin Layer
Journal Title: Современное промышленное и гражданское строительство - Year 2017, Vol 13, Issue 3
Abstract
The paper deals with the change of penetration (dП25) and softening temperature (dТr) viscous bitumen modified Elvaloem AM in the presence of polyphosphoric acid PFC-105, with its thermal and oxidation (TO), aging (163 °С) in a thin film (when its thickness such δ < δкр at which the entire volume of film involved in the process). The connection of ΔП25 and ΔТr with a conversion of bitumen, calculated from the mass loss of modified bitumen in the process of thermal oxidation has been given. The comparison of changes ΔП25 and ΔТr for the original (unmodified) and modified bitumen has been carried out and it has been suggested the usage of the developed approach for the selection of terms and preparation of bitumen modification mode asphalt and polymer concrete mixture.
