Description
Es sind bereits Verfahren zur Herstellung von bituminösen Bindemitteln für Straßenbauzwecke bekannt, bei denen Kohlenteerpech, Bitumen, geringe Mengen Alaun und fein verteilter Kalk als Füller in erwärmtem Zustand vermischt werden.There are already processes for the production of bituminous binders for road construction purposes known where coal tar pitch, bitumen, small amounts of alum and finely divided Lime can be mixed as a filler in a heated state.
Gemäß der Erfindung wird statt fein verteilten gelöschten Kalks fein verteiltes CaI-ciumearbonat, insbesondere Kreide, verwendet.According to the invention, instead of finely divided slaked lime, finely divided calcium carbonate, especially chalk is used.
to Versuche haben gezeigt, daß Baukörper, die mit Mitteln gemäß der Erfindung erzeugt sind, eine größere Druckfestigkeit besitzen als Baukörper mit Bindemitteln der bekannten Art.To experiments have shown that building structure produced with means according to the invention have a greater compressive strength than structures with binders of the known type.
Vorzugsweise werden gemäß der Erfindung etwa 2 Gewichtsteile Kreide mit etwa 1 Gewichtsteil Bitumen und Kohlenteerpech vermischt und der Alaun in Mengen von etwa ι °/b> berechnet auf die Gesamtmenge, zugesetzt, wobei der Gewichtsteil Bitumen ein- bis dreimal so groß sein kann wie der Gewichtsteil Pech. Preferably, according to the invention, about 2 parts by weight of chalk with about 1 part by weight Bitumen and coal tar pitch mixed and the alum in amounts of about ι ° / b> calculated on the total amount, added, The part by weight of bitumen can be one to three times as large as the part by weight of pitch.
Das Bindemittel gemäß der Erfindung kann zur Herstellung eines Wegebelagmaterials Verwendung-finden. In diesem Falle werden dem Bindemittel Stoffe, wie Erde, Kies, Ton, Frischschiamin, Schlick oder altes Wegebaumaterial oder Gemische dieser Substanzen, zugegeben.The binder according to the invention can be used to produce a road surface material Use-find. In this case, substances such as earth, gravel, clay, Fresh shiamin, silt or old road construction material or mixtures of these substances, admitted.
Bei einem derartigen Wegebelagmaterkl kann der Anteil an bituminösen Stoffen gering sein, und z.B. 5 °/0 betragen. '.In such Wegebelagmaterkl the proportion of bituminous materials may be low, and amount to for example 5 ° / 0th '.
Bei der Herstellung des Weigebelagmaterials wird das Bindemittel mit den Zuschlagstoffen in einem gewöhnlichen Asphaltkocher erhitzt und, falls nötig, eine geringe Menge asphalthaltiges ölflußmittel zur Verdünnung zugesetzt. Die erhaltene Masse kann, wenn sie genügend erhitzt ist, heiß als Packlage oder Unterschicht ausgelegt werden. Der Anteil des Bindemittels hängt von der Art des gewünschten Belages ab. Das Pech verleiht dem Belag Härte, während der bituminöse Bestandteil Elastizität und Zähigkeit verleiht. Für die Oberlage kann eine ähnliche Mischung wie für die Unterschicht verwandt werden, jedoch müssen gröbere Klumpen aus dem Zusatz entfernt werden. Auch wird vorzugsweise der bituminöse Gehalt im Verhältnis zu dem bei der Unterschicht verwendeten etwas erhöht.During the production of the white covering material is the binding agent with the aggregates in an ordinary asphalt cooker heated and, if necessary, a small amount of asphalt-based oil flux for dilution added. The resulting mass, if it is sufficiently heated, can be used as a packing layer or underlayer. The proportion of binder depends on the type of the desired covering. The pitch gives the pavement hardness, while the bituminous Constituent gives elasticity and toughness. A similar one can be used for the top layer Mixture as used for the underlayer, however coarser clumps must be made removed with the addition. Also the bituminous content is preferred in proportion slightly increased compared to that used for the lower layer.
Das Bindemittel gemäß der Erfindung kann für verschiedene Zwecke verwendet, werden, z. B. zur Herstellung von Kabelführungen, Böden für Eisenbahnwagen u. dgl., als Dachdeckungsmaterial, wasserbeständiges Fugenfüllmaterial für Tunnel, Röhren, Blöcke,The binder according to the invention can be used for various purposes, z. B. for the production of cable guides, floors for railroad cars and the like, as roofing material, water-resistant joint filling material for tunnels, tubes, blocks,
Säulen usw. Auch sind die Bindemittel zur Herstellung von Formgegenständen geeignet.Columns, etc. The binders are also suitable for the production of molded articles.

Gemäß einem Ausführungsbeispiel werden zur Erzeugung einer heißen bituminösen Belagmasse; die schnell bindet und eine harte,According to one embodiment, to produce a hot bituminous paving mass; that binds quickly and a hard one,
ίο wasserbeständige Oberfläche gibt und dann sofort für den Verkehr fertig ist, 3,17 kg Gasteer, 0,45 kg Hartpech miteinander verschmolzen und dieser Masse 7,25 kg pulverisierte Kreide zugesetzt. Dann werden 28 g pulverisierter Alaun zugegeben und das Ganze gründlich gemischt.ίο water-resistant surface there and then Immediately ready for traffic, 3.17 kg of Gasteer, 0.45 kg of hard pitch fused together and 7.25 kg of powdered chalk was added to this mass. Then 28 g powdered alum added and the whole thing mixed thoroughly.
Die pulverisierte Kreide kann teilweise oder ganz durch Kalkstein ersetzt werden, jedoch ist Kreide vorzuziehen.The powdered chalk can be partially or wholly replaced by limestone, however, chalk is preferable.
ao Der im Bindemittel enthaltene Teer kann durch ein passendes ölbitumen ersetzt werden, obgleich dieses weniger gute Ergebnisse liefert.ao The tar contained in the binder can be replaced by a suitable oil bitumen, although this results in less good results supplies.
