• Abstract:
  A study of the transverse profile data currently being collected under the Long Term Pavement Performance project was undertaken. The data were collected by three processes: (1) Dipstick, (2) a photographic method, and (3) straightedge used to collect rut depths. This study examined several indices for the purposes of quantifying and qualifying the transverse profiles. It is recommended that five indices be added to the National Information Management System. These indices include the area of the rut below a straight line connecting the end points of the transverse profile, the total area below the straight lines connecting the maximum surface elevations, the maximum depth for each wheel path between a 1.8-m straightedge placed across the wheel path and the surface of the pavement, and the width of the rut based on a 1.8-m straightedge. These indices were studied in order to determine typical trends by climate, surface thickness, soil type, and age. In addition, the time-series trends for each test section were studied in order to determine whether any anomalies existed and the potential causes of these anomalies.
