**3. Case studies – results and discussion**

In the preceding items, the general characteristics of the International Amazon were contextualized, with emphasis on the Brazilian Amazonia, in addition to addressing the problems faced in the construction of highways in this region. This Item presents some case studies that sought to circumvent the problems of scarcity of stone material near the construction site and the presence of soil layers with low bearing capacity in the natural foundation (subgrade) of the highways built in the Brazilian Amazonia environment.

**Figure 1** shows the locations of the case studies analyzed here.
