INVESTIGATION OF THE STRESS-STRAIN STATE OF REGENERATED ROAD SURFACES USING THE MARC-MENTAT COMPLEX

Abstract

The cost of repairing road clothes depends mainly on the cost of asphalt concrete mixtures. Currently, due to a significant rise in the price of energy resources, as well as an increase in prices for bitumen, mineral aggregates and transportation of materials to the place of their use, the issues of choosing economical technologies for repairing road clothes are of paramount importance. In recent decades, special attention has been paid to technologies of cold regeneration of asphalt concrete. These technologies are widely used both in Russia and abroad. At the same time, the question arises about the influence of layers of regenerated asphalt concrete on the strength and rigidity of the repaired pavement, the possibility of the formation of a track in it from the transport load. You can answer this question by creating a digital model of the coating structure. To create digital models of structures that are exposed to various types of impacts, computer software products in the form of finite element complexes are currently widely used.
