Use of Photographic References6.1 The photographic references3 that are part of this practice are representative of the degrees of resistance to wear of stripesof traffic paint. The examples shown in markings (Fig. 1 and ). Fig. 2 are for illus

It is therefore preferable to use one of the followinggrading methods:6.1.1.1 Select an area as representative and base the relative performance of the stripe traf
