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

Railway ballast usually uses natural crushed stone to transfer the load from the rails to the ground. However, the material has a detrimental impact on the environment as the extraction of it is a destructive process, and it is also prone to degradation and fouling in rail tracks. Therefore, this research evaluates the Basic Oxygen Furnace (BOF) slag as an alternative to traditional ballast material in the Kazakhstani railway industry. The tested BOF slags were grouped into top and bottom stockpiled with a mean age of 3–4 years and 10 years, respectively. GOST standards were mainly utilized to analyze the feasibility of the use of BOF slag in Kazakhstan. As a result, both types of BOF slag represented complete satisfaction with the proposed standards. Therefore, the potentiality of the application of stockpiled BOF slag for railway ballast material is verified.
