This paper is devoted to an analysis of experimental results on elastomeric mats applied to the pavement on the underground station “Belgrade-junction” (“Beograd-ˇcvor” in Serbian). The elastomeric composite mat taken as a support of the underground tracks is called ISOLGOMMA-M40AV. For an appropriate modelling a nonlinear viscoelasticity model is needed. The Rabotnov’s nonlinear hereditary integral equation with Abelian kernel is applied and calibrated from triangular history stress controlled testing results.
