AASHTO PP 70-14 (2017) PDF Download

AASHTO PP 70-14 (2017) is a standard practice that provides guidelines for collecting transverse pavement profiles using automated measurement devices. The practice focuses on collecting the profile with respect to a level horizontal reference in pavement surfaces. The collected profile can then be used to analyze and quantify various pavement distresses such as transverse deformation, rut characteristics, water entrapment, or edge drop-off.

The standard does not provide detailed specifications for the equipment or instruments to be used for making the measurements. Instead, it emphasizes that equipment capable of meeting the functionality requirements outlined in the practice is acceptable. The objective is to establish a standardized data set that can support a wide range of interpretation methods for characterizing pavement transverse profile characteristics.

Furthermore, the standard addresses the data collection process using a measurement device that travels at or near the posted speed limit. This ensures that the measurements are taken under realistic conditions and represent the actual pavement profile during normal traffic speeds.
