• Abstract:
  The Colorado construction communities, bonding insurance companies and the Colorado Department of Transportation (CDOT) have a variety of concerns regarding the use of long-term warranties on CDOT projects. Many of these concerns can only be answered by studying the two pilot projects constructed by CDOT containing long-term performance warranties. This report provides a brief discussion of the European warranty practices and summarizes the use of long-term warranties across the United States. In addition, the report reviews the relevant construction, specifications, selection guidelines, and bonding of these pilot projects. Implementation Based on the cost-benefit analysis and performance of the control projects versus the two warranty projects, long term warranties are not a viable option for CDOT. However, echelon paving of hot mix asphalt significantly reduced longitudinal cracking in the warranty project and may be a viable option for applicable CDOT projects.
