Abstract

Road materials are recovered and regenerated by recovering materials from the top traffic layer of highroads using a milling or scraping machine, hot or cold, and treating the materials 'in situ' or in a plant to restore their original properties. During mixing two dopes are added, one based on a regenerating prod., namely bitumen, and the other reestablishing the correct binder level to compensate for loss coased by ageing and to improve adhesion. The function of the two dopes is to deposit the mixt. of oil, resin and bitumen, without disturbing the existing structure, while restoring its plasticity and its adhesivity. The first dope whose function it is to regenerate the bitumen comprises 10% rosin, 30% anthracene oil and 60% fluidised bitumen. The second dope is a doped fluidised bitumen of variable penetration depending on the viscosity of the residual bitumen.

Description

L'invention a pour objet un procédé de régénération des matériaux routiers de récupération. The subject of the invention is a method for regenerating road recovery materials.

Actuellement, pour entretenir des routes 9 les matériaux usés de la couche de roulement de la chaussée à rénover sont9 soit recouverts par une nouvelle couche de roulement2 soit récupérés par des machines à fraiser et à raboter. Ces matériaux usés sont utilisés pour des remblais ou portés en décharge. Currently, in order to maintain roads 9, the used materials of the wearing course of the roadway to be renovated are9 either covered by a new wearing course2 or recovered by milling and planing machines. These used materials are used for embankments or landfilled.

D'une part, il n'est pas toujours possible de toujours surélever la route9 notamment dans les villes, en ajoutant la nouvelle couche de remplacement, d'autre part, il est coûteux de ne pas réutiliser les produits bitumineux et les agrégats. On the one hand, it is not always possible to always raise the road9 especially in cities, by adding the new replacement layer, on the other hand, it is expensive not to reuse bituminous products and aggregates.

Les responsables de l'entretien des routes sont confrontés à des impératifs contradictoires: - Le parc automobile ne cesse de croître, - Le coût des produits bitumineux ne cesse d'augmenter, - Les moyens financiers mis à la disposition des responsables en vue de la construction et de l'entretien des routes ne suivent pas l'augmentation des courts. Those responsible for road maintenance are confronted with contradictory requirements: - The car fleet continues to grow, - The cost of bituminous products continues to increase, - The financial resources made available to those responsible for the road construction and maintenance do not keep up with the short courts.

L'invention tend à réduire tous ces inconvénients. The invention tends to reduce all of these drawbacks.

La nécessité d'effectuer des économies sur les produits bitumineux importés et sur les agrégats ont amené l'inventeur à se pencher sur le réemploi des matériaux enrobés de récupération. The need to save on imported bituminous products and on aggregates led the inventor to look into the reuse of coated recovery materials.

L'invention permet, par son procédé, de récupérer les matériaux enrobés vieillis S de les régénérer, d'arrêter et de rattraper le vieillissement du liant au moyen d ' apport de composés adaptés, puis de réutiliser à nouveau lesdits matériaux. The invention makes it possible, by its method, to recover aged coated materials S to regenerate them, to stop and to catch up with the aging of the binder by means of the supply of suitable compounds, then to reuse said materials again.

Le procédé consiste à récupérer les matériaux de la couche de roulement de chaussée au moyen d'une machine à fraiser ou à raboter, à chaud ou à froids de les traiter ensuite en usine ou "in situ", pour leur rendre leurs qualités d'origine car le bitume, au cours des ans, a perdu certaines qualités mécaniques. The process consists in recovering the materials from the road surface by means of a milling or planing machine, hot or cold, then treating them in the factory or "in situ", to restore their qualities of origin because bitumen, over the years, has lost certain mechanical qualities.

Pendant le malaxage, on introduit deux dopes, l'un à base d'un produit régénérant, le bitume, l'autre, un liant dopé pour compenser les pertes dues au vieillissement et améliorer 1' adhési- vité. During mixing, two dopes are introduced, one based on a regenerating product, bitumen, the other, a doped binder to compensate for losses due to aging and improve adhesiveness.

La fonction de la combinaison de ces deux dopes est de déposer le mélange d 'huile et de résine sans perturber la structu re existante, tout en reconstituant sa plasticité et son adhésivité. The function of the combination of these two dopes is to deposit the mixture of oil and resin without disturbing the existing structure, while restoring its plasticity and its adhesiveness.

Le premier dope dont la fonction est de régénérer le bitume, est composé de a) 10% de résine collophane (résine naturelle ou synthétique). The first dope whose function is to regenerate the bitumen, is composed of a) 10% of rosin resin (natural or synthetic resin).

b) 30% d'huile anthracénique.b) 30% anthracene oil.

c) 60% de bitume fluidifié.c) 60% fluidized bitumen.

Le second dope a pour fonction de rétablir un dosage correct de liant, il est composé de bitume fluidifié dopé à pénétration variable en fonction de la température.  The second dope has the function of re-establishing a correct dosage of binder, it is composed of fluidized bitumen doped with variable penetration depending on the temperature.
