Definitions

  • the major difference in the mixing methods is that the first principle leads to an increased liquid content, in the quantity of particles, in the mixer, while the second principle leads to an increase in the content of particles in the liquid already placed in the mixer.
  • the i nvention, as wel l as the patent EP A2 0073 181 for producti on of asphal t mix is based on mixing by the second principle.
  • a principl e mixing method must be f urnished with detail s i n order to be applicabl e.
  • the invention differs for this reason not in principle from the mixing method in accordance with patent nr EP A2 00731 81. The difference is revealed in the details of the principle for application of the invention, determined by the result aimed at. The goal has grown when producing mix with the patented details.
  • the reason for the invention is that at the discharge of the filler in patent nr EP A2 0073181 , and other known processes the filler is not spread in a layer over the surface of the bi tumi nous liquid on the flowing coarse fraction, but in the quickest way discharged into the mixer to be distributed and penetrated through forced mixing by agitation of the materials. Further, the fine fraction is added after the fil ler and the bituminous liquid have devel oped the suspensi on, with the result that the fine fraction incalpsulates in the devel oped suspensi on of filler. These two detail s in the patented mixi ng method have shown to prevent the development of a combined suspension of the f iller and the fine fraction.
  • the prerequest for having both filler and fine fraction dispersed in a combined liquid volume is that the liquid penetrates both materials in one step.
  • the materials shall be spread in even layers over the surface of the flowing coarse fraction in the mixer.
  • the inlets are equipped for opti mizati on of interval of time between di scharges of the different materials i nto the mixer and for optimization of rates of flow at spreading, in layers, the filler and the fine fraction over the surface of the coarse fraction in accordance with the invention, to first put a layer of bituminous liquid over the surface of the coarse fraction and then powder the layer of bituminous liquid and, through penetration, bind a layer of filler after which the fine fraction is distributed in a new l ayer through further penetration of the bituminous liquid, whereby the bituminous liquid through the layers of materials unites the fill er, the fine fraction and the coarse fraction in a closed volume of liquid, a condition at which the paved mix resist pressure and strain by the hydrostatic function of the bituminous liquid obtained when the liquid is continuous through the skeleton of the aggregate.
  • Appendi x Figure 1 b) shows asphalt mix in lack of hydrostatic pressure distributi on.
  • the deformation in the specimen of test is governed by the force of gravitation.
  • Fi gure 1 a) shows asphal t mix with hydrostatic pressure distributi on and toughness.
  • the continuous resi stance against elongati on during deformation shows that the bituminous liquid is a cl osed volume.
  • the invention is a complement to patent nr EP A2, 0073181 , that has been devei opd to secure the properties of the process of mixing obtained when the liquid of mix is a closed volume.
  • bituminous liquid first is distribu ted on the surface of the coarse fraction, thereafter powdered wi th filler and then the particl es of the fine fraction are di stributed over the surface, before the bituminous liquid has broken through the layer of filler, causes that it shall be used not only on bach plants but al so on asphalt plants with continuous working mixers and on drum mixers.
