METHOD FOR PRODUCING A ROAD SURFACE AND METHOD FOR RECYCLING A ROAD SURFACE
(FR)
PROCÉDÉ DE FABRICATION ET PROCÉDÉ DE RECYCLAGE D'UN REVÊTEMENT DE VOIRIES
Abstract:
(EN)
Method for the production of a road surface, the surface of which comprises pipes of a heat exchanger device. The method is characterised in that it comprises the following steps: a) at a temperature below 160°C, spreading bituminous mixtures comprising a granular fraction, a bituminous binder, said bituminous mixtures being workable and having a workability of less than 400N, measured with a Nynas workability meter at the use temperature of the bituminous mixtures; subsequently, b) depositing pipes, said pipes having a compression strength greater than 3000 N per linear metre of pipe at 100°C, thermal expansion of less than 200.10
-6
K
-1
at 20°C, such that the pipes can be embedded even in the absence of a cooling means or pressure application means; subsequently, c) embedding the deposited pipes in the integration layer by compacting the bituminous mixtures during the workability period thereof, in order to form an integration layer comprising pipes of a heat exchanger device; and, subsequently, d) applying a surface layer thereabove for the road surface, in particular a surface course. The invention also relates to a method for recycling a road surface.
(FR)
Procédé de fabrication d'un revêtement de voiries comprenant en surface des tuyaux d'un dispositif pour échangeur de chaleur, caractérisé en ce qu'il comprend les étapes suivantes : • a) répandage à une température inférieure à 160°C d'enrobés hydrocarbonés, comprenant une fraction granulaire, un liant hydrocarboné, lesdits enrobés hydrocarbonés étant maniables, ayant une maniabilité, mesurée avec un maniabilimètre Nynas à la température de mise en oeuvre des enrobés hydrocarbonés, inférieure à 400N, puis • b) dépôt de tuyaux, lesdits tuyaux ayant une résistance à l'écrasement supérieure à 3000 N par mètre linéaire de tuyaux à 100°C, une dilatation thermique inférieure à 200.10
-6
K
-1
à 20°C de sorte à permettre leur indentation même en l'absence de moyen de refroidissement ou de moyen de mise sous pression, puis • c) indentation des tuyaux déposés dans ladite couche d'intégration par compactage desdits enrobés pendant la durée de maniabilité desdits enrobés, pour former une couche d'intégration comprenant des tuyaux d'un dispositif pour échangeur de chaleur, puis • d) application au-dessus d'une couche de surface pour revêtement de voirie, en particulier une couche de roulement; et un procédé de recyclage d'un revêtement de voirie.
