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

In the paper ways of using rubber crumb from worn tires were investigated. Possibilities of preparing Rubber-Bitumen Compounds (RBC) based rubber crumb (RC) from worn tires were studied experimentally. The physico-mechanical characteristics of paving bitumen BND 60/90 modified with rubber crumb and spent engine oil. The structure of rubber crumb was characterized by optical microscopy. Physico-mechanical characteristics of RBC were detrminated by standard methods. It is established that the quantity of entered binders depending on physical and chemical conditions, which was optimal composition of rubber-oil at a ratio of 1:1 and 3:2 and introduction to bitumen in amount of 15-25 wt.%.
