Abstract
A profiler is used to collect data on a base surface. An asphalt paver is provided with a like profiler that measures smoothness of a fresh mat of asphalt laid by the paver. The profilers measure surface elevation as a function of forward travel position. The profiler and paver position are determined by a fixed referencing system, such as the Global Positioning System (GPS). Surface elevation is plotted against position of the profiler and used to control a screed levelling a mat of paving material. A subsequent plot shows smoothness of the mat.
