This practice outlines a method for deriving pavement deformation parameters such as rut depthand cross slope in pavement surfaces utilizing a transverse profile. Detailed specifications are notincluded for equipment or software used to make the calculations. According to this standard, anyapproach that can be adequately validated to meet the functionality stipulated herein is consideredacceptable. The goal is to achieve a significant level of standardization that will contribute to theproduction of consistent pavement condition estimates without unduly restricting innovativemethods.
