Title (EN) METHOD FOR PREPARING A SURFACE COURSE AT THE SURFACE OF A HYDRAULIC COMPOSITION
(FR) PROCÉDÉ DE PRÉPARATION D'UNE COUCHE D'USURE À LA SURFACE D'UNE COMPOSITION HYDRAULIQUE
Abstract:
(EN) The invention concerns a method for forming a surface course on at least one part of a surface of a composition made from hydraulic binder to be treated, comprising the steps consisting of: a) applying a composition comprising: - at least one hydraulic binder, and - at least one aggregate, the Los Angeles coefficient LA of which is less than or equal to 0, to at least one part of a surface of a composition made from fresh hydraulic binder, b) floating the at least one part of the surface to which the composition has been applied, then c) applying a surface deactivator composition to the at least one part of the surface to which the composition has been applied, then d) curing the fresh hydraulic binder composition, then e) eliminating the uncured hydraulic binder layer on the surface, and the composition made from hydraulic binder, at least part of a surface of which comprises a surface course likely to be obtained. This surface course has improved durability.
(FR) L'invention concerne un procédé de formation d'une couche d'usure sur au moins une partie d'une surface d'une composition à base de liant hydraulique à traiter comprenant les étapes consistant à : a) appliquer une composition comprenant : - au moins un liant hydraulique, et - au moins un granulat dont le coefficient Los Angeles LA est inférieur ou égal à 0, sur au moins une partie d'une surface d'une composition à base de liant hydraulique fraiche, b) talocher la au moins une partie de la surface sur laquelle la composition a été appliquée, puis c) appliquer une composition de désactivant de surface sur la au moins une partie de la surface sur laquelle la composition a été appliquée, puis d) faire durcir la composition à base de liant hydraulique fraîche, puis e) éliminer la couche de liant hydraulique non durcie en surface, et la composition à base de liant hydraulique dont au moins une partie d'une surface comprend une couche d'usure susceptible d'être obtenue. Cette couche d'usure présente une durabilité améliorée.
