The finite element method applied to the evaluation of the stress-strain state of road constructions
The paper considers the finite element method application in the research of the stress-strain state of road constructions. Principal advantages and disadvantages of the FEM are analyzed. A possibility of sizeable inaccuracy (50 to 100 %) in determining stresses and strains in the layers of road pavements is indicated. The need to use the FEM only for the tasks where analytical solutions have not been found is emphasized.
