Description

  

  Verfahren zur Herstellung eines verkehrssichern und staubfreien Belages für Strassen  mit starken Steigungen.    Der Patentanspruch des     Hauptpatentes     kennzeichnet ein Verfahren zur Herstellung  eines verkehrssicheren und staubfreien Be  lages für Strassen mit starken Steigungen,  nach welchem auf     eine    feste Strassenunter  lage eine Schicht von mit einem bituminösen       e     Stoff präpariertem Splitter von der Körnung  0 bis 15 mm aufgetragen, hierauf eine Schicht  grober Schotter aus ebenfalls mit einem bitu  minösen     Stoff    präpariertem     Hartsteinmaterial,     ohne Beimengung von feinem Korn, aufge  bracht und     fastgewalzt    wird.  



  Als bituminöse Stoffe, welche zum Prä  parieren der     verwendeten    Baumaterialien die  nen, sind in ,den     P'atentunteransprüchen    des  Hauptpatentes speziell angeführt: Erdöl  bitumen, ein Gemisch von Erdölbitumen und  Teer, ferner ein Gemisch von     Erdölbitumen     und     Trinidadasphalt.     



  Eine weitere     Ausführungsform    des Ver  fahrens ist nun auch diejenige,     da.B    an Stelle  der     vorgängig        angeführten        bituminösen,Stoffe     zum Präparieren der verwendeten Baustoffe         bituminöse    Emulsionen benützt werden, zum  Beispiel wie folgt:  Auf die feste Strassenunterlage wird vor  erst eine Lage Splitt mit Sand von der Kör  nung 0 bis 15 mm, welche Materialien mit  einem     bestimmten        Bindemittel,    wie zum Bei  spiel     Bitumenemulsion,    präpariert: werden, in  einer Schichtstärke von 8 bis 5 cm aufge  tragen.

   Auf diese     Sp.littlage    wird alsdann  grober, ebenfalls mit einer Bindemittel, wie  zum     Beispiel        Bitumenemulsion,    präparierter       Hartsteinsthotter,        ohne    Zusatz von feinem  Korn,     in.    einer Stärke von ungefähr 8 bis  10 cm, aufgebracht und mit mittelschwerer  Walze festgewalzt, worauf der Belag sofort  dem Verkehr -übergeben     werden    kann. Als  präparierter Hartschotter eignet -sich für  diesen Belag besonders solcher aus Granit,       Gneis    oder     hartem    Sand- oder Kalkstein.



  Process for producing a traffic-safe and dust-free surface for roads with steep gradients. The claim of the main patent characterizes a process for the production of a traffic-safe and dust-free covering for roads with steep gradients, after which a layer of sliver with a grain size of 0 to 15 mm prepared with a bituminous substance is applied to a solid road surface, then a layer Coarse gravel made of hard stone material also prepared with a bituminous substance, without adding fine grain, is brought up and almost rolled.



  As bituminous substances which are used to prepare the building materials used, the following are specifically listed in the sub-claims of the main patent: petroleum bitumen, a mixture of petroleum bitumen and tar, and also a mixture of petroleum bitumen and Trinidad asphalt.



  Another embodiment of the process is that, instead of the bituminous substances listed above, bituminous emulsions are used to prepare the building materials used, for example as follows: A layer of gravel with sand is first applied to the solid road surface with a grain size of 0 to 15 mm, which materials are prepared with a certain binder, such as bitumen emulsion, for example, with a layer thickness of 8 to 5 cm.

   Then coarse hard stone sthotter, also prepared with a binding agent, such as bitumen emulsion, without the addition of fine grain, in a thickness of about 8 to 10 cm, is then applied to this chipping layer and rolled down with a medium-heavy roller, whereupon the surface immediately can be handed over to traffic. As prepared hard gravel, granite, gneiss or hard sandstone or limestone is particularly suitable for this surface.
