Abstract
The invention relates to a multicourse surfacing for pavements, in particular for pavements whose base courses are cracking, and to a method for the production of this surfacing. The surfacing according to the invention, comprising an asphaltic membrane applied to the base course of the pavement and a waring course or binder course, comprises, between the asphaltic membrane and the wearing course or binder course, at least one layer of cold mix. The method comprises applying successively to the base course of the pavement, optionally covered with a primer layer: a layer of asphaltic binder, by cold spreading, a layer of a composition containing an asphaltic binder and a granular material, a wearing course or binder course. These surfacings are particularly effective for slowing the ascent into the wearing course of cracks forming in the base course of the pavement.
