Description

Verfahren zum Herstellen von Teerschotterstraßen mit Teer und eingedickter Sulfitlaugi Es ist bekannt, die Straßen zum Binden von Staub mit einem Gemisch von Teer und Sulfitzelluloselauge zu besprengen. Hierbei wurde das Gemisch vor seiner Verwendung entweder mit Säure unter Erhitzung behandelt, oder man setzte saure und neutrale Salzlösun,-eii zu, nachdem man die Sulfitzelluloselauge vorher neutralisiert oder schwach alkalisch gemacht hatte. Ferner wurde zur Verhinderung `# von Staubentwicklung auch schon vorgeschlagen, die zu behandelnde Fläche zunächst mit eingedickter Suliitlauge zu tränken und sodann mit Teer zu besprengen. Damit sollte nehen der Bindung des Staubes durch die Ablauge und den Teer erreicht werden, daß die Ablauge genügend tief in den Boden eindringt und ihn infolge ihrer Was-Z> el seranziehung dauernd feucht hält, während der Teer gewissermaßen auf der Ablauge schwimmt und sie gegen Eintrocknen sowie Herauswaschen bei Schnee- und Regenwetter schützt. Daß hierbei die Staubbindung auf Kosten der Festigkeit des Straßenkörpers geht, ist ohne weiteres klar.Method of making tar gravel roads with tar and thickened Sulphite lye It is known to use the roads to bind dust with a mixture of Sprinkle tar and sulphite cellulose lye. Here the mixture was before his Use either treated with acid while heating, or put acidic and neutral salt solution after neutralizing the sulphite cellulose solution beforehand or made it weakly alkaline. Furthermore, to prevent dust generation, `# It has also already been suggested that the area to be treated should first be treated with thickened sulphate of liquor to soak and then sprinkle with tar. This should approach the binding of the Dust can be achieved by the waste liquor and the tar that the waste liquor is sufficient penetrates deep into the ground and, as a result of their attraction to it, permanently keeps moist, while the tar floats, so to speak, on the waste liquor and against it Drying out and washing out in snow and rainy weather protects. That here the dust binding is at the expense of the strength of the road structure is straightforward clear.
