Gehalt an verbindungsfähiger Kieselsäure.Content of bondable silica.
Patentiert im Deutschen Reiche vom 26. Juli 1910 ab.Patented in the German Empire on July 26, 1910.
Den bekannten Teerschotterdecken haften erhebliche Nachteile an. Der Erhärtungsvorgang vollzieht sich nur langsam, so daß die Straßendecke nicht unmittelbar nach der Herstellung befahren werden kann, sondern, abhängig von der Witterung, erst nach Tagen oder Wochen; außerdem aber sind derartige Decken nicht ausreichend dicht und wasserundurchlässig und nur bei trockenem WetterThe known tar ballast covers have considerable disadvantages. The hardening process takes place slowly, so that the road surface cannot be driven on immediately after construction, but, depending on the weather, only after days or weeks; but there are also such Ceilings are not sufficiently tight and impermeable to water and only in dry weather
ίο herstellbar. Ferner ist die Festigkeit des Bindemittels nur gering,, die Abnutzung daher verhältnismäßig groß, so daß sich bereits nach kurzer Benutzungszeit Staubentwickelung fühlbar macht, und durch Lastfuhrwerke Unregelmäßigkeiten auftreten, die gerade durch diese ,Teerschotterdecken vermieden werden sollen.ίο producible. Furthermore, the strength of the Binder only slightly, the wear therefore relatively large, so that already After a short period of use, the development of dust can be felt, and irregularities due to trucks occur, which are avoided precisely by this, tar gravel cover should.
Die vorliegende Erfindung vermeidet diese Ubelstände. Es geschieht das dadurch, daß dem Steinmaterial Klarschlag (Steingeschläg), Kleinschlag aus Schlacken o. dgl., außer den Bestandteilen der zur Herstellung von Teerschotterdecken bekannten Mörtelbestandteilen, wie Kalk (Hydrat), Traß u. dgl., als weitererThe present invention avoids these inconveniences. It does this because the stone material clear impact (stone impact), small impact from slag o Components of the mortar components known for the production of tar ballast coverings, like lime (hydrate), trass and the like, as another
Bestandteil Ätzkalk zugesetzt wird, bevor diese Bestandteile in den Kochgefäßen mit dem heißen Teer oder Teerprodukte, Pechöl o. dgl. behandelt werden. Durch diese Reaktionswirkung des Ätzkalkes wird einesteils die Vereinigung der Kalke und Silikate beschleunigt und ein Bindemittel größter Festigkeit erzielt, außerdem eine Verseifung des Teerproduktes herbeigeführt, so daß das Bindemittel wasserundurchlässig wird.Part of quick lime is added before using these ingredients in the cooking vessels the hot tar or tar products, pitch oil or the like. Be treated. By this reaction effect The quick lime accelerates the union of the limes and silicates and a binder of the greatest strength is achieved, as well as saponification of the tar product brought about so that the binder is impermeable to water.
Hierdurch wird der Zerstörung der Decke durch Wasser- und Frostwirkung in vollkommenster bzw. in wirksamster Weise vorgebeugt. In this way, the destruction of the ceiling by the effects of water and frost is most complete or prevented in the most effective way.
Die Festigkeit des Bindemittels gleicht aber nahezu derjenigen der Steinzuschläge, so daß die Fahrbahn ein homogenes Gebilde darstellt, welches gleichmäßig abgenutzt wird und weit geringere Abnutzbarkeit zeigt als die üblichen Teer Schotterdecken.The strength of the binder is almost the same as that of the stone aggregates, so that the road is a homogeneous structure, which is worn evenly and shows far less wear resistance than the usual tar gravel surfaces.
Ein weiterer erheblicher Vorteil des Ätzkalkzuschlags besteht aber darin, daß derselbe die Herstellung der Straßendecke auch bei nassem Wetter gestattet und ein erfolgreiches Mittel bildet, den Erhärtungsvorgang zeitlich zu regeln und nach Bedarf zu beschleunigen. Another significant advantage of quick lime surcharge is that the same the production of the road surface even in wet weather permitted and a successful one Forms means to regulate the time of the hardening process and to accelerate it as required.
Zur Herstellung solcher Decken können anstatt Traß naturgemäß auch andere Stoffe mit hohem Gehalt an verbindungsfähiger Kieselsäure benutzt werden, z. B. Puzzeolane u, dgl. Auch kann die Schotterdecke eine besondere Deckschicht aus dem angegebenen Bindemittel, warm aufgetragen und mit Sandbestreuung, erhalten.Naturally, instead of trass, other materials can also be used to produce such blankets be used with a high content of bondable silica, e.g. B. Puzzeolane and the like. The ballast cover can also have a special top layer from the specified Binder, applied warm and sprinkled with sand, is preserved.
