The recreational and touristic potential of landscapes depends not only on their natural components, but also on the functionality and safety of the associated road infrastructure, particularly forest and rural roads. This study evaluates, from an engineering perspective, the soils and aggregates used in the structural layers of such pavements, with special emphasis on their deformational and strength properties, which are essential for proper design.
The analysis focuses on determining the resilient modulus through laboratory cyclic loading tests that realistically simulate traffic and service conditions. This parameter is considered key for assessing the bearing capacity and long-term stability of unbound granular layers. In parallel, cohesion and internal friction angle obtained from direct shear tests are analysed and incorporated into numerical modelling using the finite element method.
The results highlight the need for a combined evaluation of strength and deformational properties to ensure pavement durability, reduce structural damage, and minimize erosive processes, thereby contributing to the sustainable management of both infrastructure and landscape.
