PROCÉDÉ DE RÉNOVATION D'UNE CHAUSSÉE DE CIRCULATION DE VÉHICULES
In a method for renovating a roadway, a first tack coat including a bitumen emulsion, a second coat of fibres and then a third surface coat that is a “clean” bitumen emulsion or includes an anhydrous asphalt binder, is spread by a spreading machine from bottom to top and overlaid on the milled or planed roadway. The fibres are sprayed onto the tack coat and the sprayed fibres having a maximum length of 12 cm, an asphalt mix being subsequently spread over the surface coat, the residual binder of the “clean” bitumen emulsion having a penetrability of less than 40 dmm and a ball-ring temperature greater than 50° C., the ‘clean’ bitumen emulsion including between 30% and 70% bitumen, between 30% and 70% water, and between 0.1% and 10% surfactants, stabilisers and/or additives, the percentages being by weight. The application also relates to a spreading machine.
