Repeated vehicle loads and environmental conditions cause progressive deterioration of pavement structures. These stresses act to diminish mechanical properties, resulting in structural and functional loss of the pavement. The phenomenon of reflective cracking, where existing cracks in aged pavement propagate to the surface of the newly placed reinforcement layer, is a common and challenging issue to control due to the aforementioned stresses and the short time span in which it occurs.
This study evaluates the behavior of an asphalt layer system, representing an aged layer and a reinforcement layer, by positioning a geosynthetic material at different levels of the reinforcement and subjecting the system to dynamic loading. It is observed that the geosynthetic delays the progression of a crack, achieving greater effectiveness when located as close as possible to the most tensioned fiber of the asphalt reinforcement layer.
