Figure 1. This is a typical California Profilograph that is frequently used to assess the initial smoothness of airfield pavements. This unit produces a printed trace identifying the pavement’s profile relative to the profilograph’s length.
Figure 2. This plot illustrates the settlement that has occurred over a period of eight years. This fact would not have been identified if the airport had not initially measured a baseline profile using a device that measures true profile; in this case the Auto Rod and Level.
