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

In the paper physical and mechanical characteristics of Rubber-Bitumen Compounds (RBC) on based rubber crumb (RC) from worn tires were investigated. At experiment the standard petroleum bitumen BND 60/90 modified with rubber crumb. The spent engine oil was used as additional modifying agent. Images of Scaning Electron Microscopy (SEM) showed that the RC is very low pores heterogeneous material. Physical and mechanical characteristics of rubber modified bitumen with engine oil (R:O=1:1 and R:O=3:2) corresponds to grade of paving rubber-bitumen compounds RBC 60/90, RBC 90/130 and RBC 130/200.
