A structure for the reinforcement of pavements. The structure includes at least a first group of assemblies of grouped metal filaments. These assemblies of grouped metal filaments of said first group are oriented in a first direction in a mutual parallel or mutual substantially parallel position. The assemblies of grouped metal filaments of this first group are coupled to or integrated in a substrate having a non-metal material.

An engineering construction comprising an integral multiaxial polymer geogrid at least partially embedded in a bound aggregate layer, wherein a geotextile is affixed to the geogrid, methods for producing such constructions, the constructions having improved fatigue life or reduced depth, and the use of multiaxial polymer geogrids to improve the fatigue life and/or reduce the depth of an engineering construction.

Materials and structures for absorbing energy. The materials and structures are well suited for arresting aircraft and other vehicles, although their purposes need not be so limited. Also detailed are packaging and other solutions for maintaining system integrity, especially (but not exclusively) when foam glass or other aggregate is employed and stabilizing the location of the aggregate is desired.

A method for making a reinforced concrete structure and reinforcement agents are provided. In some embodiments, the method includes obtaining a mold for the reinforced concrete structure. A lattice is formed within the mold, where the lattice includes inter-locking ringed fibers and where each inter-locking ringed fiber is a fiber formed into a ringed structure that is inter-locked with at least one neighboring inter-locking ringed fiber in the lattice. The lattice is then encased by filling the mold with concrete. In some embodiments, the reinforcement agents are a plurality of ringed fiber-structures, each of which is coiled into a ringed structure that may or may not inter-lock with at least one neighboring ringed fiber(s)-structure.

A structure for the reinforcement of pavements, said structure having a longitudinal direction and a transverse direction, said structure comprising a first group of reinforcement element, said reinforcement elements of said first group being oriented in a first direction in a mutual parallel or mutual substantially parallel position, said reinforcement elements being integrated in a substrate, whereby said substrate comprises or consists of a non-metal material with a melting temperature between 60 and 135 C.

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.
