Road with reinforced roadside

Abstract

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 collaborate in the overall resistance. It is thus proposed a “road system” in which parts that have historically been conceived in a substantially autonomous way (ground substrate platform, paving, and safety barriers) collaborate synergistically in the creation of a safe “road system” as a whole.

1 . A road system including a road substrate ( 200 ,  201 ), an asphalted road surface ( 210 ), a roadside ( 220 ) not covered by asphalt, and at least one portion of a safety barrier ( 100 ) installed on said roadside ( 220 );
 said road system also includes a reticular mesh structure ( 300 ) made up of material with good tensile strength, and suitable to be interposed under said asphalted road surface ( 210 ), and above the road substrate ( 200 ,  201 ), as well as above said roadside ( 220 ),   and being this reticular mesh structure ( 300 ) designed to cover the road substrate from side to side in its width, and to protrude beyond the area in which the asphalted road surface is to be laid ( 210 );   and wherein, said reticular mesh structure ( 300 ), in the areas which, after installation, emerges above said roadside ( 220 ), has road-edge coupling points ( 310 ) which are arranged in a row, at alternating distances or parallel to the asphalted edge of the roadway, and in its immediate vicinity, as said road-edge coupling points ( 310 ) are designed to facilitate the firm attachment of other elements of the road system.   
     
     
         2 . The road system according to  claim 1 , wherein at least some of said road-edge coupling points ( 310 ) make a coupling with some uprights ( 110 ) of said safety barrier ( 100 ), this being installed on said roadside ( 220 ) by driving the uprights in the ground. 
     
     
         3 . The road system according to  claim 1 , wherein said reticular mesh structure ( 300 ) covers also abundantly said roadside ( 220 ), projecting significantly beyond the area covered by said road surface ( 210 ), and it has additional mesh-edge attachment points ( 320 ) positioned on the outermost edges of said reticular mesh structure ( 300 ), and said further mesh-edge attachment points ( 320 ) are designed to add further ground covering elements attached to them, in order to further extend the covered terrain area, well outside the paved road. 
     
     
         4 . The road system according to  claim 1 , wherein said reticular mesh structure ( 300 ) covers abundantly also said roadside ( 220 ), projecting significantly beyond the area covered by said road surface ( 210 ), and it has additional mesh-edge attachment points ( 320 ) positioned on the outermost edges of said reticular mesh structure ( 300 ), and said further mesh-edge attachment points ( 320 ) are designed to apply ground fixing elements of said reticular mesh structure ( 300 ). 
     
     
         5 . The road system according to  claim 1 , wherein said reticular mesh structure ( 300 ) is not rigid, so as it can also be supplied in the form of rolls. 
     
     
         6 . The road system according to  claim 1 , wherein said reticular mesh structure ( 300 ) is laid under the part of the road surface ( 210 ) which is removed by milling when the road is resurfaced for maintenance purposes. 
     
     
         7 . The road system according to  claim 1 , wherein said reticular mesh structure ( 300 ) is made up of more than one reticular mesh, said reticular meshes being laid at different depth levels.
