Data confidence 70 medium

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

The article presents the results of experimental research of the thermophysical properties of asphalt concrete of various compositions based on oil bitumen and based on oil bituminous rock, which have been carried out on the laboratory unit LKT-1 using the horizontal flat layer method. It is shown that the use of oil bituminous rocks in the composition of road asphalt concrete makes it possible to obtain a material not only with the best physical and mechanical properties, but also with low thermal conductivity, which contributes to ensuring resistance to shear deformations in the road pavement during the entire period of high summer temperatures with a hot climate.
