1.1 This guide covers information for classifying the cracking type from the image collected by pavement condition survey equipment or instrumentation that measures cracking of pavement surfaces while operating at or near traffic speeds. 1.2 The measuring equipment or instrumentation, addressed by the guide, samples and stores pavement surface images while operating at or near traffic speeds. 1.3 This guide does not address equipment that operates at traffic speeds but is incapable of storing pavement surface images, such as semi-automated distress recording systems. 1.4 This guide provides classification and measurement criteria of pavement cracking for use in a range of applications. 1.5 The measurement criteria apply to the cracking of pavement surfaces. 1.6 This guide addresses the processing of pavement surface images collected by automated pavement condition survey equipment. 1.7 This guide describes pixel resolution, tile resolution, crack tile definition, orientation of crack tiles for pavement cracking classification and measurement. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
