摘要：	Pavement warranties are considered to be one of the most successful programs that can protect the agency from early failure of the pavement. At the same time they enhance industry stature by giving them additional responsibilities for performance, opportunities for innovation, and profitability. The process has been widely used in Europe to enhance the quality of pavements and to reduce the life-cycle cost of pavements. Furthermore, the process has been used in the United States and has been very successful. Potential benefits to both the agency and industry of implementing a pavement warranty include decreased construction oversight, enhanced pavement quality, and flexibility in pavement type and material selection. In addition, the agency and industry can be more productive by shifting from a passive to an active attitude toward quality (25). While there are several choices in the types of warranties that can be used for pavements, many experts feel that the most benefit can be gained through the use of short- and long-term performance warranties. In order to continue the trend toward improved pavement performance it is important to examine and implement the best practices and lessons learned by other agencies in the United States and abroad. It has been found that the successful use of pavement warranties is dependent upon the understanding of contracting methods and risk and the quality of the specifications, as well as the support of the parties involved.
