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.
Claims8
A mat made of plastic material, based on a mixture of thermoplastic materials, comprising:
- a core made of compacted plastic materials having a cohesion based on internal spot thermofusion;
- and
- a thermoplastic casing that is rigidly connected to the core by means of spot thermofusion;
- wherein the core comprises salvaged and/or waste materials, including scrap materials resulting from industrial processes and/or waste originating from a consumer market, and/or materials recovered from one or more oceans.
