Abstract

The invention relates to a modification additive for asphalt masses and to the manner of production of asphalt masses for the creation of mineral-asphalt mixtures having a high shear modulus. The essence of the invention is a modifier, characterized in that it comprises 50 to 97% of cyclopentadiene oligomers, which are dissolved in 2 to 30% by weight of alkenes with 9-11 carbon atoms in a molecule, and 1 to 15% by weight of cyclic and aromatic olefins, wherein the latter are segregation residues of other hydrocarbon fractions. The liquid asphalt mass is added to the above-mentioned modifier in a quantity of 0.1 to 15% by weight at a temperature of no more than 185ºC and kept in a liquid state for at least 15 minutes. The modified asphalt obtained in this way, together with the mineral additive, forms mineral-asphalt mixtures having a high shear modulus.

Der Gegenstand der Erfindung ist der Modifizierungszusatz für Asphaltmassen sowie die Herstellungsweise der Asphaltmassen für die Produktion von Mineral-Asphalt-Mischungen mit hohem Schermodul. Aus der Patentbeschreibung Nr. 363816 ist ein Modi-fikator für die Herstellung der Mineral-Asphalt-Mischung bekannt, der zu 50 bis 70 Gew.% aus ungesättigten Kohlenwasserstoffen C5, zu 30-45 Gewichtsprozent aus einem Stabili-sator - in diesem Falle einer Benzollösung von nichtaromatischen Ring-Kohlenwasserstoffen C4, C8 in der Menge bis zu 20 Gewichtsprozent im Verhältnis zum Benzol und zu 0-10 % aus Äthanol besteht. Aus dem polnischen Patent Nr. 317685 ist ebenfalls ein flüssiger thermostabiler Modifizierungsmittel für die heiß einzusetzenden Straßen-asphaltmassen bekannt, das aus folgendem besteht: 0,5 bis 20 Gew.-% schwersiedender Öle mit der Erstarrungstemperatur von höchstens 1O0C, 0,05 bis 5 Gew.-% an N,N-Di-(Polyoxyäthylen-)- Alkyloaminen, die in der Alkylkette 12 - 22 Kohlenstoffatome aufweisen und 4 - 15 Oxyäthylengruppen enthalten, weiterhin aus 0,025 bis 5 Gew.-% an thermoplastischem Styrol-Butadien-Styrol-Elastomer sowie bis zu 100 Gew.-% an Alkylamid-Polyaminen und/oder 2-Alkylimidazolen, die in der Alkylkette 12 - 22 Kohlenstoffatome aufweisen. Aus dem Patent Nr. 336806 ist die Herstellungsweise von einem Elastomer-Asphalt-Bindemittel bekannt, das unter anderem ein Styrol-Butadien-Styrol-Elastomer und/oder ein Styrol-Isopren- Styrol-Elastomer in der Menge von 1 bis 8 % enthält. Aus dem Pa-tent Nr. 373932 ist der modifizierte Petroleum-Asphalt bekannt, der 0,5 bis 30 Gew.-% an Fraktion des postpyrolytischen Öles enthält, die ein Nebenprodukt der Olefin-Pyrolyse von Benzinen ist und durch den Siedepunkt von mehr als 300 0C sowie durch die Erwei-chungstemperatur von mehr als 50 0C gekennzeichnet ist.The subject of the invention is the modification additive for asphalt masses as well as the way in which the asphalt masses are produced for the production of high shear modulus mineral-asphalt mixtures. It is known from patent specification No. 363816 a modifier for the production of the mineral-asphalt mixture comprising from 50 to 70% by weight of unsaturated hydrocarbons C 5 to 30 to 45% by weight of a stabilizer - in this case a benzene solution of non-aromatic ring hydrocarbons C 4 , C 8 in the amount up to 20 percent by weight relative to the benzene and to 0-10% of ethanol. . From the Polish Patent No. 317,685, a liquid thermostable modifiers for the heat to be used road asphalt masses is also known, which consists of the following: 0,5 to 20 wt .-% high-boiling oils with the solidification temperature of not more than 1O 0 C, 0.05 to 5% by weight of N, N-di- (polyoxyethylene) -alkyloamines having from 12 to 22 carbon atoms in the alkyl chain and containing from 4 to 15 oxyethylene groups, further from 0.025 to 5% by weight of thermoplastic styrene-butadiene Styrene elastomer and up to 100% by weight of alkylamide-polyamines and / or 2-alkylimidazoles having 12-22 carbon atoms in the alkyl chain. From patent no. 336806 is known the method of preparation of an elastomeric asphalt binder containing inter alia a styrene-butadiene-styrene elastomer and / or a styrene-isoprene-styrene elastomer in the amount of 1 to 8%. From patent No. 373932 is known the modified petroleum asphalt containing from 0.5 to 30% by weight fraction of the post-pyrolytic oil which is a by-product of the olefin pyrolysis of gasolines and has a boiling point of more than 300 0 C and by the softening temperature of more than 50 0 C is marked.
Der Einsatz von bekannten Modifikatoren für Asphaltmassen sowie die Herstel-Iungsweisen der Asphaltmassen fallen nach dem Vergleich aller ihrer ziemlich hoher Her-stellungskosten mit ihren durch den Schermodul beschriebenen Festigkeiteigenschaften nicht besonders günstig aus. Außerdem werden während ihrer Verlegung und Bearbei-tung bei höheren Temperaturen toxische und karzinogene Verbindungen von Benzol und seinen Derivaten in die Umwelt ausgeschieden.The use of known modifiers for asphalt compositions as well as the production methods of the asphalt compositions are not particularly favorable after comparing all their rather high production costs with their strength properties described by the shear modulus. In addition, during their installation and processing at higher temperatures, toxic and carcinogenic compounds of benzene and its derivatives are excreted into the environment.
