Abstract
Description
Die Erfindung betrifft die Verwendung von zerkleinerten teerhaltigen und mit einem zementhaltigen Bindemittel ge mischten Baustoffen.The invention relates to the use of shredded tar-containing and with a cement-containing binder mixed building materials.
In der Vergangenheit wurde Teer ebenso wie Bitumen als be währtes Bindemittel für Straßenbaustoffmaterialien einge setzt. Nach wissenschaftlichen Untersuchungen und den dar aus erwonnenen Erkenntnissen wird Teer jedoch heute als umweltschädlich eingestuft. Besondere Beachtung wird dabei den Eluatwerten beigemessen, die angeben, welche Stoffe und in welchen Mengen aus den zerkleinerten Baustoffen in Lösung gehen und somit in das Grundwasser gelangen können. Da teerhaltige Baustoffe bis zum heutigen Zeitpunkt nicht ausreichend in eine Matrix eingebunden werden können, ohne daß schädliche Elemente in Lösung gelangen, müssen die im Zuge von Erneuerungs- oder Wartungsarbeiten anfallenden teerhaltigen Baustoffe kostenaufwendig entsorgt, auf Deponien gebracht oder mit örtlicher Genehmigung aufwendig recycelt werden.In the past, tar, like bitumen, was considered to be proven binder for road building materials puts. According to scientific studies and the From the knowledge gained, however, tar is now known as classified as environmentally harmful. Particular attention is paid to this the eluate values which indicate which substances and in what quantities from the shredded building materials in Go solution and can get into the groundwater. Since tar-containing building materials have not so far can be sufficiently integrated into a matrix without that harmful elements get into solution, those in In the course of renovation or maintenance work tar-containing building materials disposed of in a costly manner Brought to landfills or expensive with local permission be recycled.
Aufgabe der Erfindung ist es, zerkleinerte teerhaltige und mit einem zementhaltigen Bindemittel gemischte Baustoffe zu verwenden und so einzusetzen, ohne daß hiervon umwelt schädliche Auswirkungen ausgehen.The object of the invention is to crushed tar and building materials mixed with a cementitious binder to use and use without environmental harmful effects.
Diese Aufgabe wird dadurch gelöst, daß die zerkleinerten teerhaltigen und mit einem zementhaltigen Bindemittel ge mischten Baustoffe als Walzbeton für die Straßen-, Wege und Platzbefestigung verwendet werden. Die in dem Walzbe ton enthaltenen Teer- und Bitumenverbindungen werden dabei derart in die Matrix eingebunden, daß ein Auslaugen der schädlichen Elemente im wesentlichen verhindert wird und die vorgeschriebenen Eluatwerte nicht überschritten wer den.This object is achieved in that the shredded tar-containing and with a cement-containing binder mixed building materials as rolled concrete for roads, paths and place fixing can be used. The one in the waltz ton contained tar and bitumen compounds integrated into the matrix in such a way that leaching of the harmful elements is essentially prevented and the prescribed eluate values are not exceeded the.
Um die Umhüllung und Einbindung der Körner in das zement haltige Bindemittel zu begünstigen, können die teerhalti gen Baustoffe auf Korngrößen von bis zu 4 mm zerkleinert werden.To wrap and incorporate the grains into the cement Favorable binders, the tar-containing crushed construction materials to grain sizes of up to 4 mm will.
Um beispielsweise besonders stark belastete zerkleinerte teerhaltige Baustoffe mit höheren Teer- und Bitumenkonzen trationen auch ohne Überschreiten der vorgeschriebenen Eluatwerte einzusetzen, können die zerkleinerten teerhal tigen Baustoffe unter Zusatz von weiteren Baustoffen, ins besondere Recycling-Baustoffen und/oder Sand mit dem ze menthaltigen Bindemittel gemischt werden. Einen weiteren Baustoff stellt beispielsweise Kies dar, der in einem be stimmten Körnungsbereich zugegeben wird. Als weiterer Bau stoff kann aber auch ein Recycling-Baustoff eingesetzt werden. Eine Art eines Recycling-Baustoffes stellt der Feinanteil in den Körnungen von 0 bis 4 mm dar, der beim Brechen von unbelasteten Straßenaufbruch anfällt. Zweck mäßigerweise können vorzugsweise 70 Gew.-% zerkleinerter teerhaltiger Baustoffe mit ca. 0 Gew.-% bis 30 Gew.-% Re cycling-Baustoffe und 30 Gew.-% bis 0 Gew.-% Sand gemischt werden.For example, to crush particularly heavily loaded tar-containing building materials with higher tar and bitumen concentrations trations even without exceeding the prescribed The shredded tarshal can use eluate values building materials with the addition of other building materials, ins special recycling building materials and / or sand with the ze ment-containing binders are mixed. Another one Building material represents gravel, for example, which in a be certain grain range is added. As another construction but a recycled building material can also be used will. One type of a recycling building material is the Fine fraction in the grain sizes from 0 to 4 mm Breaking of unencumbered road breaks arises. Purpose moderately, preferably 70% by weight can be comminuted tar-containing building materials with approx. 0% by weight to 30% by weight of Re cycling building materials and 30 wt .-% to 0 wt .-% sand mixed will.
Dem Gemisch können Additive zugegeben werden. Als Binde mittel eignet sich vorzugsweise ein Zement PZ 45.Additives can be added to the mixture. As a bandage medium is preferably a PZ 45 cement.
Im folgenden wird ein Ausführungsbeispiel der Erfindung
erläutert:
Teerhaltige Baustoffe, die bei der Straßenerneuerung ange
fallen sind, werden in einer Prallmühle auf Korngrößen von
0 mm bis 16 mm zerkleinert, wobei der Feinanteil von 0 bis
4 mm abgesiebt wird. Die zerkleinerten teerhaltigen Bau
stoffe der Körnung 4 mm bis 16 mm werden mit einem Recy
cling-Baustoff, der ein Körnungsspektrum von 0 mm bis 4 mm
aufweist, und Sand von 0 mm bis 3 mm Korngröße gemischt.
Das Mischungsverhältnis beträgt dabei 70 Gew.-% teerhal
tige Straßenbaustoffe, 10 Gew.-% Recycling-Baustoffe und
20 Gew.-% Sand.An exemplary embodiment of the invention is explained below:
Building materials containing tar, which fell during road renewal, are crushed in an impact mill to grain sizes from 0 mm to 16 mm, the fine fraction being sieved from 0 to 4 mm. The crushed tar-containing building materials with a grain size of 4 mm to 16 mm are mixed with a recycling building material, which has a grain size range from 0 mm to 4 mm, and sand with a grain size of 0 mm to 3 mm. The mixing ratio is 70% by weight of tar-containing road building materials, 10% by weight of recycling building materials and 20% by weight of sand.
Dieses Gemisch wird mit Zement und Wasser gemischt, wobei je Kubikmeter Gemisch jeweils 270 kg Zement und 68 l Was ser benötigt werden. Nach Vermischen entsteht hieraus Walzbeton, der zur Straßen-, Wege- oder Platzbefestigung bei Einhaltung der vorgeschriebenen gesetzlichen Grenz werte eingesetzt werden kann.This mixture is mixed with cement and water, whereby per cubic meter of mixture 270 kg of cement and 68 l of what are needed. After mixing, this results Rolled concrete, for road, path or square attachment in compliance with the prescribed legal limits values can be used.
