Abstract. Experimental data on the assessment of the adhesion strength of bitumen to the surface of various mineral materials are presented. graphical dependences of the adhesion of bitumen BOR 60/90 and BOR 90/130 with additives to various mineral materials are constructed. with the same acid-base characteristics of mineral materials, the adhesion strength of bitumen to the surface of a rough material (granite crushed stone) is greater than with the surface of a smoothly rolled material (gravel).

Keywords: bitumen, oil sludge, gossypol resin (fat-oil plant), technical sulfur, asphalt concrete, road pavement.
