METHOD AND APPARATUS FOR EVALUATING OR MEASURING THE CHARACTERISTICS OF THE ADHESION PROPERTIES OF A THIN LAYER APPLIED TO THE ROUGH SURFACE OF A SUBSTRATE OR ELEMENT FOR REINFORCING A BODY OF A COMPOSITE OR AGGREGATE MATERIAL

摘要

The present invention relates to a method and apparatus for evaluating or measuring the characteristics of the adhesion properties of a thin layer 1 applied to the rough surface of a substrate 2 or reinforcing elements of a substrate. body composite material or aggregate. / P P This apparatus is characterized in that it comprises a pad 3 of deformable material, means 4 to ensure a connection, permanent or non-permanent, between the pad 3 of material deformable and the thin layer 1, means for exerting a force on the pad 3 of deformable material, and means J1 .. Jn, 5 for measuring the surface deformations of the pad 3 of deformable material, deformations which depend on the behavior of the layer thin 1. / P
