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
14、tration purposes only and should not be usedfor evaluation.6.1.1 The degree of resistance to wear is likely to vary over any given area. 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
