The analysis of the sources shows that there are no analytical dependences that describe the process of soil compaction with sufficient accuracy, taking into account the repeated effects of the loads of self-propelled road rollers. The absence of such laws complicates the study of the process of multiple compaction of soil by road rollers. Since the intensity of the compaction is significantly affected by the contact time of the road roller with the ground, the time factor is of significant importance, since the movement of the road roller is a consistent loading of the soil by the first, second, third, etc. passes. Therefore, the equations on the basis of which the calculations of multiple compaction of the soil from the impact of repeated loads by road rollers to stabilize its compaction are proposed. At the same time, the number of passes to complete compaction was calculated depending on the physical and mechanical properties of the soil and from the parameters of the road roller (load, imprint area, speed, respectively, the time of contact of the wheel with the ground, etc.). |
