  • Abstract:
    This project developed a draft specification for asphalt concrete pavement construction smoothness testing. The South Dakota Road Profiler, smoothness measuring equipment already owned by SDDOT, was used as the testing device. Since the objective of this testing was to assure road smoothness, automated means were devised to find localized roughness, namely bumps and dips. The cornerstone to this method lies in this project's development of the telescoped rolling straightedge statistic. An attempt was made to economically justify implementation of this specification. Based upon existing SDDOT road profile data, these results were obtained: SDDOT asphalt roads are already constructed very smoothly; and extremely smooth asphalt concrete roads lose their edge in smoothness within seven years of construction. Nevertheless, the assumption of a 10% smoothness increase at construction was sufficient to justify specification implementation. Based on other states' experience, specification implementation does result in smoother constructed roads and increased contractor incentive and awareness in regard to this objective. With the implementation of this specification, SDDOT will be able to assess and improve the current level of smoothness attained at construction.
