The article presents a method of experimental research and created stand with metrological equip-ment that allows to simulate the complex process of milling asphalt concrete samples by force and coordinate closure. As a result of the research, regression equations describing the milling parame-ters of asphalt concrete samples, were obtained. It is established that during the transition from the power (elastic) closure of the technological system to the rigid (coordinate) one, milling errors de-crease by up to 15 % and their spread is up to 30 %. The developed method for restoring the road surface can be applied in practice not only within Kazakhstan, but outside the country, as wellDOI

Based on the analysis of the layouts of existing automated road cutters, the dominant factors determining the change in the relative position of the working bodies of the machine and the road surface, during the milling of the road surface with variable track height are determined, which causes a decrease in the evenness of the profiled surface of the road surface. The concept of presenting a road milling cutter as an automated road transport and technological manipulator that corrects the level of dimensional adjustment by vertical movements of the working body is proposed, based on of which a new design of an automated road milling cutter, for repairing road surfaces with variable References trackage with the possibility of adjusting the working body in height, has been developed. The feasibility of the transition from elastic (force) closure to rigid (coordinate-kinematic) closure of the track milling process scheme has been substantiated and proved, which allows not only to reduce the current average deviations of the height of the milled surfaces, but their variations from the average, as well. The transition to coordinate and kinematic closure makes it easier, both from the point of view of building a drive system and from the point of view of programming processes, to implement the process of operation of automated road cutters.Квартиль
