This article proposes a method of calculation
for evaluating stresses and strains in the track structure.
This condition is calculated by modelling the single elements
composing the structure, considering the loads and
the number of traffic repetitions, the characteristics of the
materials, and the environmental conditions.
The method can be used both in the design phase to optimize
the choice of the materials to be used and in the operation phase
to verify the real service life of the structure in the presence of
substantial variations in the data presumed in the design phase.
The method has been validated with the experimental
data collected by R.F.I. The method has been applied to
evaluate the service life of a track, considering the layer mechanical
characteristics and the air temperatures.
