ASTM E1656-06

1.1 This guide covers information for classifying the measurement capability of pavement condition survey equipment or instrumentation that measures longitudinal profile, transverse profile or 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 measurement data while operating at or near traffic speeds.

1.3 This guide does not address equipment that operates at traffic speeds but is incapable of measuring profile or individual crack characteristics, such as response-type roughness measuring systems and semi-automated distress recording systems.

1.4 This guide provides measurement criteria and classification for use in a range of applications.

1.5 The measurement criteria apply to longitudinal profile, transverse profile, or the cracking of pavement surfaces.

1.6 This guide does not address the processing of measured data.

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.
