Abstract
The article presents the results of experimental research of the thermophysical properties of asphalt concrete of various compositions based on oil bitumen and based on oil bituminous rock, which have been carried out on the laboratory unit LKT-1 using the horizontal flat layer method. It is shown that the use of oil bituminous rocks in the composition of road asphalt concrete makes it possible to obtain a material not only with the best physical and mechanical properties, but also with low thermal conductivity, which contributes to ensuring resistance to shear deformations in the road pavement during the entire period of high summer temperatures with a hot climate.
