Abstract
A method for manufacturing a road surfacing on the surface pipes of a heat exchanger device by a) spreading asphalt mix comprising a granular fraction, a hydrocarbon-based binder at a temperature below 160° C., wherein the asphalt mix has a workability of less than 400 N, b) depositing the pipes, said pipes having a crushing strength greater than 3000 N per linear metre of pipe at 100° C., a thermal expansion less than 200·10−6 K−1 at 20° C. in such a way as to enable their indentation even in the absence of cooling means or pressure application means, c) indenting the deposited pipes into said integration layer by compacting said asphalt mix during the workability period of said asphalt mix, to form an integration layer comprising the pipes of a heat exchanger device, and d) applying a surface layer there above for the road surface.
