Surface dressing - Test methods - Part 2: Visual assessment of defects

EN 12272-2:2003 发布历史

This European Standard is applicable to all surface dressings (roads, airfields and other trafficked areas) andspecifies qualitative and quantitative methods of the visual assessment of defects of surface dressing.The results of the qualitative evaluation carried out by visual assessment when specified shall be reported in annexA.This is a rapid practical test and may be specified asThe primary test so that ifThe results are obvious or arewithout any doubtThe more time consuming quantitative test method may be avoided.The quantitative test methodshall be carried out when specified andThe table of results in annex B reported.The visual assessment reports for both methods have identical records and thus both may be used to checkThespecification for visual assessment of defects (prEN 12271一).The rapid qualitative test methods is dependent onthe skill and experience of the operator andThereforeThe repeatability andThe reproducibility values will not be asprecise, butThe convenience of the method and lack of disruption to traffic will ensure its use.The national application document may state whether either or both or sequentiallyThe qualitative and quantitativetests are to be used and may relateThis to types of site (for example lightly trafficked roads may not be required tobe quantitatively assessed).
