AASHTO PP 68-14 (2017) PDF Download

AASHTO PP 68-14 (2017) is a standard practice that provides guidelines for collecting images of pavement surfaces for the purpose of distress detection. The focus of this standard is on utilizing automated methods for data collection, rather than specifying detailed equipment specifications. Instead, it emphasizes the need for equipment to meet the functionality requirements outlined in the standard.

The standard recommends collecting images while traveling at or near highway speed to ensure data is captured under normal driving conditions. The collected data should cover the entire driven lane in the travel direction to provide an accurate representation of pavement conditions.

The overall goal of this standard is to promote standardization in collecting pavement condition data to enhance consistency and accuracy in pavement condition estimates, while also allowing room for innovation.
