Abstract
In this paper, finite element modeling was used to establish a mechanical structural model of asphalt concrete cutting processes. When road milling machines come into contact with various aggregate particles, patterns of changes in mechanical data are obtained and studied. The relationship between friction resistance and operational parameters has been determined. Random simulations of different aggregate particles in asphalt concrete samples were performed using Python software and Monte Carlo method. After the simulation, the results were applied to digital software to plot the variation curve of the friction resistance of the cutter to obtain the rule for its variation with different coefficients, and the combinations of the optimal operating parameters of the milling planer were summarized.
