ABSTRACT
Permanent way selection is achieved according to the repeated load and environmental factors in the
road superstructure, and stone mastic asphalt (SMA) coatings are one of the selected coating types on
roads with heavy vehicle traffic. Determining the behavior of roads under load is a complex
construction. Generally, tests are applied on the performance of the road with laboratory and field
experiments. Since the test method usually requires many experiments and costs, it is important to
support the behavior of road pavements under different conditions with numerical analyzes as well.
In particular, the stress-strain relations in the layer transitions of the road pavement are better
understood by numerical analysis. In this study, the engineering properties of SMA coatings in
different axle load applications were investigated, and the stress-strain relations in different layers
were evaluated. As a result, less stress-deformations were observed in the transitions to the lower
layers.
