Abstract (en)

[origin: EP0440562A1] The subject of the invention is a multi-layered roadway covering, in particular for roadways whose foundations are cracked, and a method for producing this covering. <??>The covering according to the invention, constituted by a bituminous membrane applied to the foundation of the roadway and by a running layer or a connecting layer, is characterised in that it comprises, between the bituminous membrane and the running or connecting layer, at least one layer of cold moulded cladding. <??>The method consists in successively applying to the roadway foundation, possibly coated with a surfacing layer:   - a layer of bituminous binder,   - in the cold condition, a layer of a compound containing a bituminous binder and an aggregate,   - a running or connecting layer. <??>These coatings are particularly effective for slowing down the rising through the running layer of cracks forming in the roadway support.
