Stress strain state of asphalt concrete pavements of steel bridges

The object of research is the stress-strain state of asphalt concrete pavements of steel bridges with an orthotropic slab under traffic load. Research is necessary because one of the main problems of steel bridge deck pavements is the formation of longitudinal cracks in asphalt concrete above the main beams of superstructures. At the same time, there are no instructions in the engineering standards to prevent the appearance of such a crack. The lack of clear instructions, in turn, is because the stress-strain state of the roadway of metal bridges has features that have not been studied sufficiently.
