In recent years, highway agencies and constructors have used improved construction techniques and materials for better pavement quality. However, newly constructed portland cement concrete pavement surfaces are not always being built to the desired level of ride quality; thus, there is a need for an improved smoothness specification to insure the best riding quality. This paper documents the development and evaluation of end-result smoothness specifications for portland cement concrete pavements in Texas. Based on available equipment and prior studies, the California Profilograph was selected as the instrument for use in developing the specification. Because there are several types of California profilographs, the study team compared two instruments by two different manufacturers. This paper presents the results of this comparison, along with a methodology for defining a recommended specification.
