The Nebraska Department of Roads (NDOR) currently has an incentive system which rewards contractors for quality of materials and workmanship documented during the construction of flexible pavement. The system presented in this report rewards contractors for producing flexible pavement with good long-term performance characteristics. After studying pavement warranties and long-term quality control measures used by other agencies plus consulting with the NDOR and several pavement contractors, researchers proposed an incentive system for flexible pavement that is based upon two performance measures, rutting and flushing. Three years after construction, flexible pavement with rutting less than 4mm and flushing less than twenty percent would qualify for a monetary incentive. Three projects built in 2002-2003 were subsequently analyzed where construction quality incentives ranged from 3.7% to 5.7% were paid. Based upon rutting data measured annually by the NDOR, only one of these projects would have qualified for the proposed incentive. A suggested minimum for the incentive was established as 6%, since an incentive paid three years later will have to exceed the incentive paid immediately after construction to interest contractors. A quality incentive program of this type has the potential to provide many of the benefits of pavement warranties, best value contracts and performance-based contracting procedures with significantly less legal entanglements. / Supplementary Notes: Sponsored by the Nebraska Deprtment of Roads, Lincoln, NE.
