The Texas Department of Transportation plans to implement smoothness specifications based on profilograph testing for all asphalt concrete paving projects as part of its construction quality control/quality assurance program. Smoothness specifications have been developed for newly constructed asphalt and portland cement concrete pavements. In a move to develop a similar specification for asphalt concrete overlays, the Texas Transportation Institute (TTI) was asked to evaluate the applicability of the existing flexible pavement smoothness specifications for the quality control and quality assurance of pavement rideability on overlay construction projects. This study was intended to provide the state with the information necessary to evaluate the improvement in ride quality that may be expected from placement of asphalt overlays, particularly for thin overlays [38 to 51 mm (1.5 to 2 in.)], which are generally constructed in Texas. To collect data to determine whether the existing specification can be implemented for overlay construction, TTI monitored a number of overlay projects during the 1994 calendar year. Profilograph measurements were made during these projects before any surface preparation, after surface preparation, and after placement of the asphalt concrete overlay. All of the projects monitored involved thin overlays. The data collected indicate that the existing smoothness specifications can be implemented on overlay projects, provided that appropriate surface preparations (e.g., milling, level-ups) are conducted to correct existing surface distresses before placement of the overlay.
