METHOD OF EXAMINATION BITUMEN ADHESION TO VARIOUS MINERAL MATERIALS

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).
