This report presents the findings of a research project to investigate whether the relative contributions of the structural layers to rutting in a hot mix asphalt (HMA) pavement can be determined from an analysis of its transverse surface profile. The report presents a recommended method for estimating the relative contributions of pavement layers to total rutting. The report will be of particular interest to engineers in the public and private sectors with responsibility for the design, construction, maintenance, and rehabilitation of HMA pavements
