NosaukumsThis European Standard specifies the classes of permissible percentage tolerances for the defects which may occur after the construction of a surface dressing. This standard is applicable to all surface dressings (roads, airfields and other trafficked areas).

The measurement of visual assessment after twelve months gives an appreciation of the durability of the surface dressing.
