Description

  

  Verfahren zur Herstellung eines Asphaltbelages mit einer gegenüber der Farbe  des     gewöhnlichen        Asphaltes    helleren Färbung.    Die bekannten Asphaltbeläge weisen       dunkelgraue    bis schwarze Farbe auf, und  sind infolgedessen nachts und vor allem bei  nächtlichem Regenwetter sehr schlecht be  leuchtet und     unsiehtig    für den Verkehr.  



  Diesem Übelstand wird durch das Ver  fahren gemäss vorliegender Erfindung da  .durch abgeholfen, dass ein pulveriges     Aufhel-          lungsmaterial,    beispielsweise Metall- oder  Glaspulver verwendet wird, das man vor  zugsweise auf die Oberfläche des gewöhn  lichen Asphaltbelages aufbringt, um eine     Be-          lagsoberfläche    mit.     heller    Färbung zu er  zeugen.  



  Die Verteilung des Materials erfolgt, wie  erwähnt, in pulveriger Form, zum Beispiel  in Staub-, Sand- oder auch in gröberer Form,  und es kann in einer dieser Formen allein  oder in mehreren gemischt aufgebracht wer=  den. Auch können verschiedene     Körnungen     des     Materials    nacheinander aufgebracht wer  den.    Das Material, zum Beispiel Metallpulver,  wird zweckmässig auf den noch heissen As  phalt vor oder nach dem Feststreichen oder  Walzen     desselben,    aufgestreut oder in den  selben     'eingerieben;    es kann auch während  dem Komprimieren des Belages aufgestreut  werden.  



  Ferner kann das     Metallpulver    auch der  Asphaltmasse während ihrer Zubereitung     züi-          gesetzt    werden.  



  Als Metall wird hauptsächlich Alumi  nium verwendet, doch können auch andere       Metalle    Verwendung finden. aber auch     Gla     eignet sich für diese Zwecke.  



  Das auf der Oberfläche des Asphalt  belages haftende Material gibt letzterer     eine     grössere     Rauhheit,    vermindert also die Mög  lichkeit des     Ausgleitens    der     Strassenbenützer     und erhöht     ausserdem    die Widerstandsfähig  keit des     Belages    gegen Abnutzung.



  Process for producing an asphalt pavement with a lighter color compared to the color of normal asphalt. The known asphalt pavements are dark gray to black in color, and as a result, they are very poorly lit and not visible to traffic at night and especially in rainy weather at night.



  This inconvenience is remedied by the method according to the present invention by using a powdery whitening material, for example metal or glass powder, which is preferably applied to the surface of the usual asphalt pavement in order to include a pavement surface. lighter in color.



  As mentioned, the material is distributed in powder form, for example in dust, sand or even coarser form, and it can be applied in one of these forms alone or in several mixed forms. Different grain sizes of the material can also be applied one after the other. The material, for example metal powder, is expediently sprinkled or rubbed into the hot asphalt before or after it is brushed or rolled; it can also be sprinkled on while the covering is being compressed.



  Furthermore, the metal powder can also be added to the asphalt mass during its preparation.



  The main metal used is aluminum, but other metals can also be used. but Gla is also suitable for these purposes.



  The material adhering to the surface of the asphalt pavement gives the latter a greater roughness, thus reducing the possibility of road users slipping and also increasing the resistance of the pavement to wear and tear.
