Description

  

  Belag für Strassen und Plätze.    Gegenstand der vorliegenden Erfindung  ist ein Belag für Strassen und Plätze aus  Bitumen oder einem mit Bitumen gebundenen  Mineralgerüst.  



  Durch örtliche Setzungen, ferner durch  Einwirkung von Frost und Wasser im Bau  grund entstehen in     derartigen    Belägen mit  der Zeit Risse, die eine vorzeitige Zerstörung  des Belages herbeiführen. Ferner bilden sich  in derartigen Belägen infolge Einwirkung  der Verkehrslasten mit der Zeit Wellen,  indem in der Belagsmasse seitliche Verschie  bungen auftreten. Die Erfindung sucht nun  diesen Mängeln zu begegnen durch die Ein  bettung von Armierungsorganen von gegen  über dem Belagsmaterial höherer Zugsfestig  keit.  



  Nachstehend werden     Ausführungsbeispiele     des Erfindungsgegenstandes beschrieben.  



  Als Armierungsmaterial kommen beson  ders zur Herstellung von Zugorganen, z. B.  von Seilen,     Schnüren    und Drähten geeignete  natürliche und künstliche Gespinstfasern  bezw. Metalle in Frage. Die die biegsamen    Armierungsorgane bildenden Zugorgane kön  nen dabei zu geflochtenen, geknüpften oder  geklammerten Netzen und Geflechten verar  beitet oder derart einzeln im Belag verlegt  sein, dass sie sich weder an den Kreuzungs  stellen noch anderswo gegenseitig     berühren.     



  Vorteilhaft werden die Armierungsorgane  etwa auf halber Höhe zwischen einer Unter  schicht und der Belagsoberfläche angeordnet.  Bei zweischichtigen Belägen empfiehlt es  sich, die     Armierungsorgane        in    der untern  Hälfte der     obern        Belagschicht,    also der Deck  schicht, anzuordnen. Bei drei- und     mehr-          schichtigen        Belägen        ist    es empfehlenswert,  die     Armierungsorgane    in die mittlere Schicht       bezw.    in ,die mittleren Schichten     einzubetten.     



  Die geschilderten     Armierungsorgane    eig  nen sich für alle Beläge der     Bitumengruppe     sowie für Beläge aus einem mit Bitumen ge  bundenen Mineralgerüst.



  Surface for streets and squares. The subject of the present invention is a covering for streets and squares made of bitumen or a mineral framework bound with bitumen.



  Local subsidence and the action of frost and water in the building cause cracks in such coverings over time that lead to premature destruction of the coverings. Furthermore, as a result of the action of traffic loads, waves form in such coverings over time, as lateral shifts occur in the covering mass. The invention now seeks to counteract these shortcomings by embedding reinforcement members of higher tensile strength than the covering material.



  Exemplary embodiments of the subject matter of the invention are described below.



  As reinforcement materials come FITS for the production of tension members, z. B. of ropes, cords and wires BEZW suitable natural and artificial woven fibers. Metals in question. The tension members forming the flexible reinforcement members can be processed into braided, knotted or stapled nets and braids, or they can be laid individually in the covering in such a way that they neither meet at the intersections nor touch one another anywhere else.



  The reinforcement members are advantageously arranged approximately halfway between a lower layer and the pavement surface. In the case of two-layer coverings, it is advisable to arrange the reinforcement elements in the lower half of the top layer, i.e. the top layer. In the case of three- and multi-layer coverings, it is advisable to place the reinforcement elements in the middle layer or in to embed the middle layers.



  The reinforcement elements described are suitable for all coverings of the bitumen group as well as for coverings made of a mineral structure bound with bitumen.
