Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper examines the effect of gas oil fraction extraction depth from fuel oil on the physicochemical and performance properties of road bitumen. The study's novelty lies in establishing the relationship between the seven-component chemical group composition of heavy residues and their oxidation kinetics. It has been experimentally demonstrated that using feedstock with a nominal viscosity (VU80) in the range of 20-80 s (corresponding to fractions of 480-525 °C) enables the production of bitumen that simultaneously meets the requirements of ASTM D946, EN 12591, and ST RK 1373. The paper substantiates an optimal "viscosity range" for processing non-standard feedstock, ensuring increased resistance of the finished product to thermal-oxidative aging.
