Abstract: The present invention relates to a stable mat (10) based on thermoplastic materials, comprising a core of compacted plastics (14), the cohesion of which is provided by spot thermal fusion (18) in the core of the mass, and a skin obtained by surface thermal fusion and/or a thermoplastic shell (12) firmly attached to the core by localized thermal fusion. Such a mat may serve as bases for civil engineering constructions, for the distribution of loads in the case of loose, unstable, or marshy soils, the stabilization of embankments or of unstable soils, earthquake-resistant protection of foundations of structures and composition of absorbent ballasts of railroads. They may also be used for the manufacture of prefabricated road elements.
Abstract: A method for applying to a support multiple articles held in protective elements comprises the following steps: thermoforming a thin plastic material sheet to provide a plurality of hollow recesses therein, introducing into the recesses a plurality of articles, applying to the recesses a closure film, coupling to the closure film a multilayer strip including a first film element which can be bound to the closure film, an adhesive layer and a siliconized paper layer, the method further including a die-cutting step for die-cutting material portion encompassing the recesses and removing the waste material including all the mentioned layers, with the exception of the siliconized paper layer.
