The City of Raleigh in North Carolina has recently undertaken an innovative implementation of a Pavement Management System using automated data collection (ADC) to identify crack deterioration for input to the pavement management system (PMS). Unlike the traditional methods, the City is adopting a new methodology to measure crack density calculated as crack length in linear feet per square yard for use in the pavement management system. More specifically, these crack densities are measured for short data collection segments (approximately six feet) per transverse zone (as defined in AASHTO R-85). This project helped in the development of the new ASTM Standard Practice for Generating Pavement Surface Cracking Indices from Digital Images (E3303-21), which will aid others in future ADC initiatives. The presentation will describe this new and forward-thinking data collection and subsequent pavement management methodology so that other interested agencies can look into adopting ADC to obtain more accurate and repeatable data in the future.
