This practice outlines the procedures for collecting images of pavement surfaces utilizing automated methods for the purpose of distress detection for both network- and project-level analysis. Detailed specifications are not included for equipment or instruments used to collect the images. According to this standard, any equipment that can be adequately validated to meet the functionality stipulated herein is considered acceptable. The goal is to achieve a significant level of standardization that will contribute to the production of consistent pavement condition estimates while not unduly limiting innovation.
The images are to be collected utilizing a platform traveling at or near the prevailing highway speed.
The data collected should cover the entire driven lane in the travel direction.
