Description

506 581 9' den ledas av fillerfasen, vilket med uppfinningen uppnås genom att först sprida fillern över bitumenlagret, som finns på grovfraktionens yta och sedan tillföra finfraktionen innan vätskan brutit igenom lagret av filler, för att obundet filler skall damma ner finfraktionens matrerial och leda penetrationen genom finfraktionen. 506 581 9 ' it is led by the filler phase, which with the invention is achieved by to first spread the filler over the bitumen layer, which is on the surface of the coarse fraction and then add the fine fraction before the liquid broken through the layer of filler, to unbound filler shall dust down the material of the fine fraction and lead the penetration through the fine fraction.

Problemen med asfaltbeläggningar är tendensen att spårbilda och spricka. När filler och finfraktion båda är part av den slutna vätskevolymen, blir tryck och dragkrafter fördelade på hydrostatisk väg. Limfasens fördelningen av tryck skyddar beläggningen mot överbelastning och spárbildning, vid höga temperaturer och limfasens seghet skyddar mot sprickbildning vid låga temperaturer.The problems with asphalt pavements are the tendency to rutting and crack. When filler and fine fraction are both part of the closed fluid volume, pressure and tensile forces are distributed hydrostatic pathway. The adhesive phase distribution of pressure protects the coating against overload and rutting, at high temperatures and the toughness of the adhesive phase protect against cracking at low temperatures.

Bilaga Figur 1a) visar asfaltmassa som saknar hydrostatisk tryckfördelning. Provkroppens deformation är påverkad av gravitationen. Figur 1b) visar asfaltmassa med hydrostatisk tryckfördelning och seghet. Det kontinuerliga motståndet mot töjning under deformation visar att bitumenvätskan är en sluten ' volym.Appendix Figure 1a) shows asphalt mass that lacks hydrostatic pressure distribution. The deformation of the specimen is affected by gravity. Figure 1b) shows asphalt mass with hydrostatic pressure distribution and toughness. The continuous resistance to elongation during deformation shows that the bitumen liquid is a closed one 'volume.

Uppfinningen har upptäckts vid använding av patent nr EP, A2, 0073181 när det inträffat att inställda tidintervaller gjort patent nr EP, A2, 0073181 till gränsfall till uppfinningens förfarande. Kunskap om hur optimering skall ske har inte funnits tillgänglig eftersom man arbetat efter hypotesen att den sammanlagda större volymen hos suspensionen med filler måste vara utvecklad innan finfraktionen kunde inrymmas.The invention has been discovered using patent No. EP, A2, 0073181 when it has happened that set time intervals have been made Patent No. EP, A2, 0073181 to limit cases to the invention procedure. There has been no knowledge of how to optimize available because one worked according to the hypothesis that it total larger volume of the suspension with filler must be developed before the fine fraction could be accommodated.

Finfraktionen blir därmed del av filler suspensionen.The fine fraction thus becomes part of the filler suspension.

Uppfinningenmedför att fillret används som ledare av bitumenvätskan genom finfraktionens material för att både filler och finfraktion skall inrymmas i samma suspensionsvolym.The invention means that the filler is used as a conductor of the bitumen liquid through the fine fraction material to both filler and fine fraction shall be contained in the same suspension volume.

Uppfinningens förfarande är en komplettering till förfarandet enligt patent nr EP, A2, 0073181, som tillkommit för att säkerställa de egenskaper i massan som uppnås med den slutna vätskevolymen.The process of the invention is a complement to the process according to patent no. EP, A2, 0073181, which was added to ensure the properties of the mass achieved with the closed the volume of fluid.

Förfarandet enligt uppfinningen där bitumenvätskan först skall fördelas på ytan av grovfraktionen, därefter överpudras med filler och sedan fördela finfraktionspartiklarna över ytan, innan bitumnvätskan bryter genom lagret av filler, medför att förfarandet kan tillämpas inte bara på satsblandarverk, men BNSDOCID: 3 506 581 också på asfaltverk med kontinuerligt arbetande blandare och trumblandarverk, om materialen tillsättes i ordning och manér som föreskrives i uppfinningen.The method according to the invention where the bitumen liquid is to first distributed on the surface of the coarse fraction, then powdered with filler and then distribute the fine fraction particles over the surface, before the bitumen liquid breaks through the layer of filler, causing that the procedure can be applied not only to batch mixers, but BNSDOCID: 3 506 581 also on asphalt plants with continuously operating mixers and drum mixer, if the materials are added in order and manner prescribed in the invention.
