Description

Straßenbelagmaterial Es ist bereits bekannt, mit Asphalt als Bindemittel Straßendecken herzustellen, die ein einigermaßen helles Aussehen haben, wodurch @es leichter ist, des Verkehrs auf .der Straße und der seitlichen Begrenzung derselben selbst bei schlechter Beleuchtung ansichtig zu werden, als wenn die Straßendecke von dunkler Farbe ist. Zu diesem Zweck wurden bereits .verschiedene Sträßenbelagmaterialien vorgeschlagen, die indessen gewisse Nachteile (aufweisen, da sie entweder zu .durchlässig sind, wodurch sie das Bitumen auf,-saugen und@zu dunkel werden, oder aber nur unter Schwierigkeiten in den ,erforderlichen Mengen und zu einem erschwinglichen Preise beschafft werden können.Road paving material It is already known to use asphalt as a binder To produce pavements that have a reasonably light appearance, which @it is easier, the traffic on .the street and the lateral limitation of the same to be seen even in poor lighting than when the road surface is dark in color. Various road surface materials have already been used for this purpose suggested, which, however, have certain disadvantages, since they are either too permeable which means that they absorb the bitumen, suck it up and @ become too dark, or just below it Difficulties in the required quantities and at an affordable price can be procured.

Erfindungsgemäß. werden die erwähnten Nachteile dadurch beseitigt, daß das Straßen: belagmaterial ganz oder teilweise aus gebranntem Flint hergestellt wird.According to the invention. the disadvantages mentioned are eliminated by that the road: paving material wholly or partly made of burned flint will.

Roher Flint ist ein leicht zu beschaffendes Material, das in sehr großen Mengen unbenutzt daliegt, weil man bisher keine genÜg.enden Verwendungsmöglichkeiten dafür gefunden hat, und das sich nicht als Straßenr belagmaterial eignet, weil bei der Zerkleinerung desselben scharfe, schneidende Kanten entstehen.Raw flint is an easy-to-source material that works in very lying there unused in large quantities because there are currently no sufficient uses has found it, and that is not suitable as a road surface material, because at the comminution of the same produces sharp, cutting edges.

Es ist bereits bekannt, daß@ man durch Brennen des im Naturzustande dunklen Flints ohne übergroße Kosten ein weißes Material erhält. Dasselbe eignet sich erfindungsgemäß vorzüglich als Straßenbelagmaterial; es saugt das, Bitumen nicht auf und ergibt bei der Zerkleinerung keine scharfen Kanten.It is already known that by burning the in the state of nature dark flints can be given a white material at no excessive cost. Same thing excellent according to the invention as a road surface material; it sucks that, bitumen does not appear and does not produce any sharp edges when shredded.

Bei der Aufbringung einer Straßendecke aus dem neuen Material kann man in der Weise verfahren, daß, im aufzutragenden Gemisch z. B. q.0% gebrannter Flint geeigneter Körnungen zur Anwendung gelangen. Das fertige Material wird wie gewöhnlich auf die Fahrstraße aufgebracht und @erscheint sogleich. ganz dunkel. Bei der allmählichen Abnutzung der oberen Asphaltschicht werden die Flintkörner ganz weiß, @erscheinen, so daß. die Straßendecke hell und reflektierend wird. Durch das Vermischen des gebrannten Flints mit Materialien eines anderen Härtegrades erhalten die verschiedenen Punkte der Straßendecke eine ungleiche Härte, wodurch die Gefahr, daß Wagen b.ei nasser Witterung auf der Fährstraße gleiten, verringert wird.-.When applying a road surface from the new material can proceed in such a way that, in the mixture to be applied, for. B. q.0% fired Flint of suitable grits are used. The finished material will be like usually applied to the driveway and @appears immediately. completely dark. As the upper asphalt layer gradually wears down, the flint grains become completely knows @appear so that. the road surface becomes bright and reflective. By the mixing of the fired flint with materials of a different degree of hardness the different points of the road surface have an unequal hardness, which creates the risk of that wagons slide on the ferry road in wet weather is reduced.
