    • Abstract:
      Smoothness specifications are applied by almost all state transportation agencies, including the Virginia Department of

      Transportation (VDOT), to promote the overall quality and optimum ride quality of pavements. VDOT has a ride specification

      that provides a pay adjustment (either incentive or disincentive) depending on the smoothness of the final paved surface.

      VDOT’s ride specification also has a provision to waive the disincentive and apply the incentive part only to projects where

      project geometry, etc., is perceived to make it difficult for the contractor to achieve the desired ride. When applied, the waiver is

      intended to encourage the contractor to apply additional efforts to improve the ride for otherwise difficult projects.

      In late 2011, VDOT’s executive leadership formed an Asphalt Quality Task Force to identify and recommend specific

      achievable measures to improve the quality of the asphalt paving in Virginia. The task force agreed to consider the proposal to

      make an incentive-only provision the default for projects that would otherwise not qualify for the regular ride specification

      application. This study documented and critically reviewed the pilot application of the incentive-only provision for rideability on

      selected asphalt resurfacing schedules for VDOT’s 2013 construction season. Several lane-miles of control sites were compared

      with the “incentive-only” sites to determine if the prospects of added incentives led contractors to alter their paving procedures in

      pursuit of a higher quality ride.

      There was no statistically reliable distinction between the achieved quality of the incentive-only and control sites. Further,

      it was found that the originally proposed incentive-only provisions did not provide any meaningful benefit to VDOT or

      contractors. The study developed a revised incentive-only specification and further recommended that the proposed provision be

      applied to a wider range of projects in VDOT’s 2015 construction season.
