Description
Oppfinnelsen vedrører et pulverformet bindemiddelkonsentrat, samt dets anvendelse. The invention relates to a powdered binder concentrate, as well as its use.
I de siste år ble det kjent forsterkede bestrebelser på å muliggjøre tilbakeføring av anvendte materialer i produksjons-prosessen (recyklering). Knapphet og dyrgjøring av de klass-iske gateleggestoffer bitumen og mineralstoffer, samt økolo-giske tanker, førte til gjenanvendelse av nedgåtte gatebelegg. Teknologiene ble utviklet til å føre de fremkomne "brukt-stoffer" til en hensiktsmessig utnyttelse. Kjent er gjenanvendelse på stedet, dvs. på Uggestedet (Recykling in place) In recent years, increased efforts have been made to enable the return of used materials in the production process (recycling). The scarcity and increase in the price of the classic road paving materials bitumen and mineral materials, as well as ecological tanks, led to the reuse of degraded road pavements. The technologies were developed to bring the resulting "used materials" to an appropriate utilization. Recycling in place is known, i.e. at Uggestedet (Recycling in place)
og opparbeidelse i stasjonære anlegg (Recykling in plant).and processing in stationary facilities (Recycling in plant).
I begge tilfeller kjenner man anvendelsen av bare brukt asfalt, og tilsetning av friske tilslagsstoffer til bruktmateri-ale. Avgjørende er kvaliteten av den dannede blanding og den derav resulterende anvendelsesmulighet. I mange tilfeller lar det seg med recykleringsasfalt bare å foreta underordnede gate-legningsforholdsregler, f. eks. landeveislegging, undersjikt-ing, osv. In both cases, the use of only used asphalt is known, and the addition of fresh aggregates to used material. Decisive is the quality of the mixture formed and the resulting possibility of application. In many cases, with recycled asphalt it is only possible to take secondary road-laying precautions, e.g. road laying, underlayment, etc.
Oppfinnelsens gjenstand er et pulverformet bindemiddelkonsentrat som består av et bitumenøst bindemiddel, et silan, resp. en silanblanding og et bærestoff. The object of the invention is a powdered binder concentrate consisting of a bitumenous binder, a silane, resp. a silane mixture and a carrier.
Bindemidlet kan være en fra jordolje fremstillet destillasjonsbitumen ifølge DIN 55 946. Likeledes kan bindemidlet være stenkulltjære, som f. eks. en karbobitumen, eller en videre-utviklet tjærebitumen. I en utførelsesform ifølge oppfinnelsen kan bindemidlet være en blanding av en fra jordolje fremstillet destillasjonsbitumen ifølge DIN 55 946, og en stenkulltjære. The binder can be a distillation bitumen produced from petroleum according to DIN 55 946. The binder can also be coal tar, such as e.g. a carbon bitumen, or a further-developed tar bitumen. In an embodiment according to the invention, the binder can be a mixture of a distillation bitumen produced from petroleum according to DIN 55 946, and a coal tar.
Ifølge DIN 52 000 av 1980 forblir som residu og jordoljedestill-asjonen destillasjons- eller gatelegningsbitumen hvis betegnel-se består av bokstaven B og et tall som angir den midlere pene-trasjon i jQ mm. Den i Bundesrepublik Tyskland vanligste normen bitumen er B 25 (hård), B 45, B 65, B 80 og B 200 (myk). Tilsvarende de "Technischen Lieferbedingungen fiir Bindemittel auf Bitumen- og Teerbasis" (august 1980) lar det seg også an-vende videreutviklede tjærebitumen. According to DIN 52 000 of 1980, what remains as residue and the petroleum distillation is distillation or road-laying bitumen whose designation consists of the letter B and a number indicating the average penetration in jQ mm. The most common standard bitumen in the Federal Republic of Germany is B 25 (hard), B 45, B 65, B 80 and B 200 (soft). Corresponding to the "Technischen Lieferbedingungen fiir Bindemittel auf Bitumen- og Teerbasis" (August 1980), further developed tar bitumen can also be used.

This mixture can be prepared both by mixing the pure zeolites and also in direct synthesis using the trap method. Mixtures can be prepared directly, can be mixtures of zeolite A and P, zeolite A and X, of zeolite A and hydroxysodalite, of zeolite P and X, or zeolite P and Y. In a preferred embodiment, the binder concentrate can contain a mixture of zeolite X and zeolite P in a ratio of 80-5 to 20 - 95.
En slik blanding kan eksempelvis fremstilles ifølge DE-OSSuch a mixture can, for example, be prepared according to DE-OS
20 28 163, side 15, tabell 3, eksempel 3, ved hjelp av en fellingsfremgangsmåte. 20 28 163, page 15, table 3, example 3, using a precipitation method.
Fremstilling av den pulverformede bindemiddelkonsentrat iføl-ge oppfinnelsen kan foregå ved enkel sammenblanding av de enkelte bestanddeler. Production of the powdered binder concentrate according to the invention can take place by simple mixing of the individual components.
Bindemiddelkonsentratet ifølge oppfinnelsen kan anvendes til forbedring av brukt asfalt. Q Det tilsettes derved som tilslagsstoff til brukt asfalt resp. brukt asfaltholdig blandings-gods, f. eks. ved recyklering av nedgått gatebelegg. Videre kan bindemiddelkonsentratet ifølge oppfinnelsen anvendes som tilslagsstoff ved fremstilling av bituminøse bygningsstoffer som støpeasfalt, valseasfalt, takbaner, fugemasser, sparkel-masser, takbelegg, isoleringsmasser, undergulvbeskyttelse, korrosjonsbeskyttelse, antilimmasser, etc. The binder concentrate according to the invention can be used to improve used asphalt. Q It is thereby added as an aggregate to used asphalt or used asphaltic mixed goods, e.g. by recycling degraded street pavement. Furthermore, the binder concentrate according to the invention can be used as an aggregate in the production of bituminous building materials such as cast asphalt, rolled asphalt, roofing sheets, joint compounds, putty compounds, roof coatings, insulating compounds, subfloor protection, corrosion protection, anti-adhesive compounds, etc.
Det pulverformede bindemiddelkonsentrat ifølge oppfinnelsen muliggjør en tildosering såvel på stedet (f. eks. ved Remix-fremgangsmåten) som også på det stasjonære blandeanlegg (Batch-Plant eller Drumm-Mix). Tilsetningsmidlet kan utgjøre 1-5 vekt-% referert til brukt asfaltdel. The powdered binder concentrate according to the invention enables dosing both on site (e.g. in the Remix method) and also at the stationary mixing plant (Batch-Plant or Drumm-Mix). The additive can amount to 1-5% by weight, referred to the asphalt part used.
Følgende forbedringer inntrer:The following improvements occur:
Fortynning av forhårdet bruktasfalt.Dilution of hardened used asphalt.
Forbedring av klebefastheten av det samlede bindemiddel. Improvement of the adhesive strength of the combined binder.
Denne forbedring av bruktasfaltblandingen muliggjør anvendelse av bruktasfalt for større krav, på grunn av forbedring av fortettbarheten,økning av standfasthet ved høye utetempera-turer, samt forbedring av kuldeegenskapene. This improvement of the used asphalt mixture enables the use of used asphalt for greater requirements, due to the improvement of compactability, increase of stability at high outside temperatures, as well as improvement of the cold properties.
Ytterligere fordeler ved bindemiddelkonsentrater ifølge oppfinnelsen er: Further advantages of binder concentrates according to the invention are:
Enkel lagring av transport i silo og i sekker.Simple storage of transport in silos and in sacks.
Ubegrenset holdbarhet.Unlimited durability.
Enkel dosering og derved ingen nedsettelse av asfaltblande-anleggytelser. Simple dosing and thus no reduction in asphalt mixing plant performance.
Bindemiddelkonsentratet ifølge oppfinnelsen kan eksempelvis fremstilles som. følger: De syntetiske kiselsyrer og den pulverformede zeolitt haes ved normaltemperatur i en ltikket blander og gjennomblandes fullstendig. Den varme og flytende, med silan modifiserte bindemiddel påsprøytes på bærestoffet eller inndyses. The binder concentrate according to the invention can, for example, be prepared as follows: The synthetic silicic acids and the powdered zeolite are placed at normal temperature in a sealed mixer and thoroughly mixed. The hot and liquid, silane-modified binder is sprayed onto the carrier material or injected.
