Cam rollers can be used to break up cold asphalt pavements. 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 highwayDOI

Практическое значение
Based on the experimental tests of the cam rollers during the reconstruction of the Gulshad-Akchatau highway, it seems possible to draw the following conclusions: mathematical dependencies have been obtained that allow calculating the necessary efforts for destruction of the old asphalt concrete pavement by the cam rollers during the reconstruction of roads, taking into account the physical and mechanical properties of the medium and the geometric dimensions of the working body; an engineering method has been developed for calculating the main parameters of a cam roller (mass of the rink, dimensions and number of cams necessary for the destruction of an asphalt concrete pavement with the production of References lumpy scrap of a given size) used to open and destroy the old asphalt concrete pavement of reconstructed roads; to reduce the rolling resistance of the roller, the cams are hinged to ensure their free exit from the pavement. The pilot tests of the cam roller, during the destruction of the old asphalt concrete pavement during the reconstruction of the road, confirmed the efficiency and reliability of theoretical calculations and scientific points made in the work.Квартиль
