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

A review of the literature on the use of thermal power plants (TPPs) in the production of asphalt concrete was conducted. The advantages and disadvantages of asphalt concrete coatings are analyzed. According to experts, the reason lies in the violation of construction technology. And, in principle, the topics of ensuring compliance with construction standards and legislative regulation are among the most relevant in the construction of roads in Kazakhstan.The features of the use of asphalt-resin-paraffin waste from oil fields and ash of the Kyzylorda thermal power plant as part of asphalt concrete in road construction are considered. The construction of the pavement with the use of asphalt concrete based on the composite binder system "Bitumen - asphalt concrete-tar-paraffin waste (ARPW) - TPP ash" has been developed. Due to the stratification of the concrete mixture, the cement milk will be separated from the coarse aggregate, so the upper layer, which experiences the main loads and impacts from the wheels of cars, turned out to be without the main coarse aggregate. This subsequently led to its rapid wear and the formation of a rut. Cement concrete coating with all the positive aspects described below and obvious, and here, too, there are disadvantages of these types of coating, it is not the inability to open traffic immediately after the completion of construction and the need for expansion joints. The author reveals not only the advantages of asphalt concrete coatings, but also the disadvantage of asphalt mixtures in practical use in highways.
