Validating Proposed Definitions for Comparable Pavement Cracking Data

NCHRP Web-Only Document 288: Standard Definitions for Common Types of Pavement Cracking proposed a set of discrete definitions for common cracking types in asphalt- and concrete-surfaced pavements. The definitions classify cracks based on information extracted from images collected by highway-speed data collection vehicles, including feature orientation, length, width, location, and other relevant factors. These definitions are intended to harmonize and facilitate comparable measurement and interpretation of pavement cracking across the highway community. Research is needed to validate the proposed definitions and develop a practice in AASHTO format for their use by highway agencies. The objectives of this research are to (1) validate the proposed definitions developed in NCHRP Web-Only Document 288 for cracking in asphalt- and concrete-surfaced pavements, (2) suggest any needed refinements, adjustments, and/or additions to the proposed definitions, and (3) develop draft language for consideration by AASHTO to incorporate the research findings in AASHTO R 85, Standard Practice for Quantifying Cracks in Asphalt Pavement Surfaces from Collected Pavement Images Utilizing Automated Methods, in a format specified by the AASHTO Committee on Materials and Pavements.
