Resumen de: WO2023148592A1
The field of application of the present invention relates to the best practices that can be adopted in the construction of roads, also taking into particular consideration the fact that not only the road surface needs adequate consolidation, as it is normally done, but also the docks. In fact, the roadside must be considered part of the "road system", and its characteristics have a great influence on the overall road safety. In particular, the "road system" according to the invention provides that, before laying the asphalt surface, a reticular mesh structure is laid over the road surface made up of material with good tensile strength, and this reticular structure is designed to cover the entire roadbed from side to side in its width, and to protrude significantly beyond the area in which it is envisaged to lay the asphalt, so that, once the asphalt has been laid, said reticular structure protrudes from the asphalted roadway so as to cover, at least in part, even the roadside. Furthermore, said reticular structure, in its edges, which, after installation, run parallel to the edge of the road, and externally to the paved site, is designed to facilitate the firm coupling of other elements of the "road system". Said reticular mesh structure 300 is retained by the overlying road surface 210, but not only. In fact, since it envelops the entire strip of the elevated ground on which the road is built, it allows the entire mass of terrain on which the entire "road system" is built to
