In Kazakhstan, about 70 % of roads have such coatings. It is most effective to open at temperatures above 20 °C. To reduce the traction force and uniform movement of the roller, it is necessary to eliminate the resistance of the coating to the exit of the cams, when rolling the drum by pivoting the cams in the roller's direction. The reliability of the theoretical studies' results was confirmed by production tests of the cam rollers during the opening of the asphalt concrete pavement on the Gulshad-Akchatau highway.
