MANUAL FOR CONDITION RATING OF FLEXIBLE PAVEMENTS--DISTRESS MANIFESTATIONS

Rating of pavement surface condition is used on one form or another by most highway authorities as a measure of the ability of the pavement to continue to provide required service to the public. The surface condition rating scheme used in Ontario is based on two interelated measures-riding quality and distress manifestations. Riding quality can be measured quantitatively by mechanical devices such as Roughometers and Profilometers. Distress manifestations are categorized and illustrations of each catagory are provided to lend uniformity to reporting and interpretation. In addition, descriptions of the density of occurrence and the severity of the particular distrsss manifestation are made to conform with standard words which express the relative density or severity on a scale which may be quantified from 1 to 5. Examples of use of these descriptions of distress manifestations are given. Guidelines and photographs are provided to control usage of the standard words. Probable causes of each distress manifestation are presented, together with comments on progressive deterioration or other behavior which might affect remedial treatment.
