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

Cam rollers can be used to break up cold asphalt pavements. In Kazakhstan, about 70 % of roads have such coatings. It is most effective to open at temperatures above 20 °C. To reduce the traction force and uniform movement of the roller, it is necessary to eliminate the resistance of the coating to the exit of the cams, when rolling the drum by pivoting the cams in the roller's direction. The reliability of the theoretical studies' results was confirmed by production tests of the cam rollers during the opening of the asphalt concrete pavement on the Gulshad-Akchatau highway.
