• Abstract:
  Road surface roughness in the proximity of the pavement-bridge interface may lower riding quality and induce excessive dynamic wheel loads on highway structures. Twenty-one bridge sites in four Texas State Department of Highways and Public Transportation Districts, Lubbock, Houston, Austin, and San Antonio, are selected for study. The Surface Dynamics Profilometer is utilized to measure roadway profiles. Dynamic vehicular tire forces induced by three types of vehicles at two specified speeds are estimated using a computer simulation model. Possible causes and typical patterns of surface irregularities are identified and classified, and various treatment methods are examined. A dynamic load index is developed to assess ride quality and predict subjective ratings.
