Abstract:Наведено результати досліджень процесів сумісного окиснення гудрону і важкої смоли піролізу, а також модифікування товарного бітуму важкою смолою піролізу. Встановлено принципову можливість використання важкої смоли піролізу в процесах виробництва нафтових бітумів.
“…Roofing materials must have durability, water resistance, heat resistance and be resistant to atmospheric influences [1]. Also, they must be elastic enough to prevent cracks and tears from occurring due to shrinkage, temperature and other deformations of the insulated constructions.…”
The method of obtaining a bituminous composition, which can be used in the manufacture of cold-applied roofing materials using rubber crumb, is developed. The optimum content of components of a three-component bitumen composition is established.

A comparison of the ability of modifiers of different classes to slow down the aging processes occurring in petroleum bitumen during pavement operation is presented in the article. Oxidized and residual road bitumens were used as research objects. Determination of resistance to hardening under the influence of heat and air was performed by the RTFOT method. Samples of oxidized bitumen with the addition of petroleum polymer resins with hydroxyl functional groups and heavy pyrolysis resin were found to have the best resistance, while for residual bitumen the highest resistance was observed with the introduction of heavy pyrolysis resin and sulfur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
