  • a modifier to be mixed with bitumen is produced separately, transferred to an asphalt concrete plant, and an appropriate amount of the modifier is fed into a pug-mill mixer during mixing the aggregates, fillers and bitumen therein.
  • This type has its merits in convenient transferring and handling, but it must satisfy both conditions of having the fed modifier be melt-mixed homogeneously with bitumen within a short mixing time (45 to 50 seconds) and having the homogeneously modified bitumen be coated onto all the surface of aggregates and fillers evenly.
  • the conventional plant-mix type (Korean Patent Application No. 1999-0007510), in order to solve the above-mentioned problems, makes each component into fine powders (under 1 mm) so that the polymer composition may be melted in very short time.

  • Waste materials are generally used for the constitutional materials of the compositions, but it is preferable to use recycled materials in the case where the waste materials are difficult to be obtained, or virgin materials as the last alternatives from the aspect of saving costs and improving properties of the materials by recycling wastes and using large amounts.
  • bitumen modifiers of the invention is characterized in that the compositions are fed into a compounding machine (a banbury mixer, a compression kneader, a single or twin screw extruder), and under high temperature and pressure, the mixture is reacted by shear mixing vigorously to form a homogenous material.
  • the material is passed through the extruder die of an extruder and prepared into particles. After freeze-drying, the particles are stored.

  • the present invention uses a low-cost waste foamed polymer resin or waste polymer resin as much as possible, except for the inevitable case of using a virgin material.
  • the use amount of the waste material can be increased to 3 to 30 wt% due to its low cost, while that of the virgin material is 3 to 8 wt%, based on the amount of a plasticizer.
  • the improvements in properties of modified bitumen and the recycling effect of the industrial waste products can be achieved at the same time.
  • a specific resin corresponding to the component of the composition according to the present invention is selectively used. As such, it is possible to manufacture an economically effective additive by using the waste products. Furthermore, a banbury mixer or a compression kneader mixer adopted for the first time in the present invention to manufacture additives can be used for mixing all forms of waste materials such as powders, films, particles, sheets, lumps and scraps, therefore using waste materials became convenient.
  • the term "material for improving high temperature performance” stands for a thermoplastic polymer resin having relatively high glass transition temperature (-15 to +1O 0 C), and such materials are not deformed easily even when the temperature of the pavement is 6O 0 C or higher in summer, but melted to high viscosity liquid only when the temperature reaches 100 0 C or higher in general.
  • the term "polymer for improving the low temperature performance” stands for a thermoplastic elastomer or rubber having double bonds.
  • the glass transition temperature of these materials is generally in the range of -20 to -45 0 C; therefore the materials maintain the flexibility without becoming rigid at a temperature below O 0 C.
  • the materials having flexibility in low temperature is excellent in crack resistance, thus it is suitable in cold regions since the low temperature performance of bitumen improves when mixed with the bitumen.
  • the viscosity of the materials is lowered at a high temperature. Therefore there is a problem of generating plastic deformation easily.
  • Vinyl acetate portion of an EVA copolymer is reacted with a thermoplastic elastomer having double bonds, while ethylene portion of EVA has affinity with PE (thermoplastic polymer), PE has affinity with wax component of bitumen, and starch which has affinity with bitumen and reduces melting point can be added to complete the composition for forming a homogeneous substance as a whole. Therefore, in the embodiment, PE and EVA as a thermoplastic polymer (for improving the high temperature performance), SBS and SBR as a thermoplastic elastomer having double bonds (for improving the low temperature performance), bitumen as a plasticizer, starch, organic fatty acid (for reducing melting point and for affinity) and the like can be a component of the composition.
  • Another disadvantage of the plant-mix type is the matter of whether the additives are capable of melting instantly to be mixed suitably with bitumen to form a homogeneous material.
  • the conventional method tries to solve the above-mentioned problems by pulverizing each components of the composition separately into fine powders and simply mixing the components in powder phase. This is because the smaller the particles are the easier the melting is to be carried out.
  • a mixing chamber when feeding the fine powders into a mixing chamber, there may be a problem in homogeneous mixing of the components due to the floating powders that has not been dropped completely or difference in density between the powder and the aggregates.
  • the melting point and the viscosity of the modifier are reduced and an appropriate amount of plasticizer is added to the composition so that the modifier is easily melted and at the same time well mixed with bitumen. Further, a great amount of filler is added thereto.
  • the modifier is evenly coated with the filler, thus the problems of dropping completely or unevenly mixing can be solved.
  • the filler is readily coated on the modifier during mixing, it is possible to mix the components in short time.
  • the composition is formed into a single substance via the processes of manufacturing modifiers, and the substance is pulverized into fine particles to solve the above-mentioned problems. In the case where this method is not enough, the fine particles may be further pulverized into fine powders to solve the problems.
  • the plasticizer of the inventions in general, must have relatively smaller molecular weight compared with polymers and excellent affinity with bitumen to achieve the desired object.
  • bitumen is classified as a plasticizer; in fact, by using bitumen as a part of a plasticizer, the improvement in the affinity between a modifier and bitumen can be accomplished by the bitumen plasticizer contained in the modifier. Best Mode for Carrying Out the Invention

Abstract

L'invention porte sur des compositions de modificateurs d'asphalte artificiel destinées à résoudre simultanément les problèmes de déformation plastique à haute température et les diverses craquelures à basse température qui sont générées sur des revêtements de sol en asphalte artificiel dans une région où les étés sont chauds et les hivers froids. L'invention porte également sur des procédés de fabrication de ces compositions. La composition du modificateur de l'invention comprend 1 à 300 parties en poids d'au moins un composant issu d'un groupe de résines polymères alvéolées (résiduaire ou recyclé) et d'un groupe polymère thermoplastique (résiduaire, recyclé ou vierge); 1 à 300 parties en poids d'au moins un groupe provenant d'un groupe élastomère (résiduaire, recyclé ou vierge) à double liaison et 1 à 300 parties en poids d'au moins un groupe provenant d'un groupe d'agents plastifiants (résiduaire, recyclé ou vierge); et également, si besoin, 1 à 1500 parties en poids d'une charge de remplissage ou 1 à 100 parties en poids d'un agent de réaction chimique. Le procédé de fabrication du modificateur est caractérisé en ce que la composition est amenée dans une machine de préparation de mélanges (un malaxeur Banbury, un malaxeur à compression, une extrudeuse à vus unique ou double vis) pour réaliser un mélange à cisaillement vigoureux, à haute température et haute pression, de façon à obtenir un matériau homogène, le faire passer ensuite dans une filière d'extrudeuse pour former des particules et conditionner les particules dans divers sacs, tels que des sacs en polyéthylène.
