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 this article were investigated ways of production of Rubber-Bitumen Compounds (RBC). The physico-mechanical characteristics of paving bitumen BND 60/90 modified with rubber crumb from spent tire and spent engine oil. The structure of rubber crumb was characterized by optical microscopy and physico-mechanical characteristics of rubber-bitumen compounds are determined by standard methods. It established that the quantity of entered rubber-oil depending (ratio 3:2) on physical and chemical conditions. 15-25 wt.% rubber-oil modified bitumens were according to variety standard of RBC.
