USING THE KIR OF THE KARASYAZ-TASPAS DEPOSIT AS A COMPONENT OF HOT ASPHALT CONCRETE

Abstract

Natural bitumen has long been used in road paving, but in recent years, the demand for it has decreased. However, the use of natural bitumen in the road surface is gaining popularity again. Natural bitumen has a high content of asphaltenes and a higher molecular weight compared to petroleum bitumen. For the purpose of promising application of natural bitumen as road construction materials, studies were conducted on the selection of compositions based on oil-bitumen rocks of the Karasyaz-Taspas deposit.
