Description
Verfahren zur Herstellung einer Schotterstraßendecke unter Verwendung einer Emulsion aus Asphalt o. dgl. Die Erfindung betrifft ein Verfahren zur Herstellung einer Schotterdecke unter Verwendung einer Emulsion aus Asphalt o. dgl. mit großer Lagerbeständigkeit. Das Verfahren besteht darin, daß die Straßendecke nach Aufbringen der Emulsion und Abwalzen mit einer Flüssigkeit besprengt wird, die ein rasches Ausscheiden des Bitumens aus der Emulsion herbeiführt, so daß eine wasserundurchlässige, dünne Schutzhaut gebildet wird.Method of making a gravel road surface using an emulsion of asphalt or the like. The invention relates to a method for producing a gravel surface using an emulsion of asphalt o. The like. With a large Shelf life. The method consists in that the pavement after application the emulsion and rolling is sprinkled with a liquid that has a rapid Causes the bitumen to precipitate out of the emulsion, so that a water-impermeable, thin protective skin is formed.
Um diese Schutzhaut härter zu machen, als das ausgeschiedene Bitumen an sich ist, können der Emulsion Härtemittel bekannter Art, z. B. Wasserglas, und der Nachbehandlungsflüssigkeit chemisch darauf einwirkende Stoffe zugesetzt werden.To make this protective skin harder than the excreted bitumen per se, the emulsion can hardeners of known type, e.g. B. water glass, and substances that act chemically on it are added to the aftertreatment liquid.
Die bekannten Bitumenemulsionen scheiden entweder vorzeitig, z. B. irn Transportbehälter, das Bitumen aus, was _Klumpenbildungen zur Folge hat, oder die Ausscheidung des Bitumens tritt zu langsam ein, in welchem Falle wiederum die verwendete Emulsion auf der Straße noch lange Zeit löslich bleibt. Hierdurch können Schäden verursacht werden, und 'mit Emulsionen behandelte Straßen sind zuweilen nach kurzer Lebensdauer schon verfallen.The known bitumen emulsions either leave prematurely, e.g. B. In the transport container, the bitumen out, which leads to the formation of lumps, or the excretion of the bitumen occurs too slowly, in which case again the The emulsion used remains soluble on the street for a long time. This allows Damage is caused, and roads are treated with emulsions at times expire after a short service life.
Das Verfahren nach der Erfindung soll derartige Übelstände beseitigen. Nach üblichem und bekanntem Verbrauch der Emulsion auf der Straße wird eine Nachbehandlung mit Stoffen vorgenommen, die dort, wo sie mit der Emulsion in Berührung kommen, ein plötzliches Ausscheiden des Bitumens aus der Emulsion herbeiführen. Es entsteht so eine dünne Bitumenhaut, eine Schutzdecke, unter welcher zweckentsprechend langsam die Ausfällung der Emulsion vor sich geht. Fällt Regenwasser auf diese Schutzhaut, so kann es nicht hindurchdringen.The method according to the invention is intended to eliminate such inconveniences. After the usual and known consumption of the emulsion on the road, an aftertreatment is required made with substances that come into contact with the emulsion, cause the bitumen to suddenly separate from the emulsion. It arises such a thin bitumen skin, a protective cover, under which, appropriately, slowly the precipitation of the emulsion is going on. If rainwater falls on this protective skin, so it cannot penetrate.
Es ist von Vorteil, wenn die Schutzhaut eine größere Härte und Festigkeit erhält, ohne daß die Elastizität der darunterliegenden, sich langsam ausscheidenden Bitumenmengen gemindert wird. Man setzt zu diesem Zwecke der Emulsion Wasserglas o. dgl. zu und mengt der Nachbehandlungsflüssigkeit Stoffe, wie Metallsalze (Magnesia), bei. Dadurch, daß diese Stoffe chemisch auf das zugesetzte Härtemittel einwirken, wird die Schutzhaut gehärtet.It is advantageous if the protective skin has a greater hardness and strength maintains without the elasticity of the underlying, slowly excreting Bitumen quantities is reduced. For this purpose, waterglass is added to the emulsion or the like and adds substances such as metal salts (magnesia) to the aftertreatment liquid, at. Because these substances act chemically on the hardening agent added, the protective skin is hardened.
Eine Schotterstraße wird nach dem vorstehend beschriebenen Verfahren in ähnlicher Weise hergestellt wie bisher. Die Emulsion wird über die von Schmutz gereinigte und mit Steinsplitt überworfene alte Steindecke der Straße gegossen. Erforderlichenfalls wird hierauf die Decke abgewälzt. Sodann wird die Nachbehandlung durch Besprengen mit der Scheidungsflüssigkeit vorgenommen.A gravel road is made according to the method described above manufactured in a similar way as before. The emulsion gets over that of dirt The old stone ceiling of the street, cleaned and covered with stone chippings, was poured. If necessary, the ceiling is rolled onto this. Then the aftercare made by sprinkling with the divorce fluid.
