• Abstract:
  The Iowa Department of Transportation (IDOT) evaluated the PAS I Road Survey System from PAVEDEX, Inc., of Spokane, Washington. This system uses video photography to identify and quantify pavement cracking and patching distresses. Comparisons were made to procedures currently used in the State. Interstate highway, county roads and city streets, and two shoulder sections were evaluated. Variables included travel speeds, surface type and texture, and traffic control conditions. Repeatability and distress identification were excellent on rigid pavements. Differences in distress identification and the effect of surface textures in the flexible test sections limited the repeatability and correlation of data to that of the IDOT method. Cost data indicates that PAVEDEX is capable of providing comparable results with improved accuracy at a reasonable cost, but in excess of that experienced currently by the IDOT. PAVEDEX is capable of providing network level pavement condition data at highway speeds and analysis of the data to identify 1/8-inch cracks at approximately 2-3 lane miles per hour with manual evaluation. Photologging capability is also included in the unit.
