AASHTO R 41-05 (2015) PDF Download

The AASHTO R 41-05 (2015) standard outlines the procedure for obtaining pavement profile data using the Face Technologies Dipstick®. This manual method provides precision measurements of relative elevation differences in the pavement. The dipstick is a tool that offers higher accuracy and efficiency compared to traditional rod and level surveys for profiling pavement surfaces.

The standard describes the procedures for measuring both longitudinal (along the direction of traffic flow) and transverse (perpendicular to the direction of traffic flow) profiles using the dipstick. Operators with experience can obtain up to 500 readings per hour using this practice, indicating that the method is efficient for data collection.

This standard is essential for ensuring consistent and reliable measurement of pavement profiles. It provides guidance on using a specific tool and establishes a standardized approach for obtaining accurate and high-quality profile data. Compliance with this standard ensures that the measurement process is consistent across different projects and enables better analysis and comparison of pavement profiles.
