Comparative analysis of experimental methods to assess the resistance of milling road asphalt concrete

Abstract

Abstract The paper is devoted to the comparative analysis of experimental evaluation of cutting resistance of road asphalt concrete to cutting elements with cylindrical carbide tips, which are widely used in rotors of road milling machines. The paper shows the comparison of the results obtained from the study of cutting of typical asphalt concrete with a single cutter on a pendulum stand and on a stand with a mechanical low-speed drive of the cutting element. The advantages and disadvantages of both methods are determined and provided in the paper. The conclusions obtained allow us to recommend reasonably the methods of research of strength indicators of asphalt concrete from the point of view of cutting resistance to cutting with working bodies of road machinery.
