Final Scope

There is currently no national standard for pavement warranty projects. Some state departments of transportation (DOTs) have developed their own warranty specifications. These specifications vary in terms of pavement type, warranty type, warranty period, risk allocation items, performance evaluation methods, enforcement methods, etc.

The objective of this synthesis is to document the use and effectiveness of performance-based pavement warranties by DOTs. The study will focus on both asphalt and concrete pavement projects with warranty periods of at least one year.

Information to be documented includes (but is not limited to):
• Performance criteria and threshold values for warranty specifications;
• Identification of suitable candidates for warranty;
• Warranty periods for different types of pavements and treatments;
• Methods for measuring pavement conditions relative to warranty performance criteria;
• Aspects of warranty enforcement (e.g., warranty guarantee, bonds, reporting out and notification of exceeding thresholds, conflict resolution methods);
• Extent of use relative to total pavement program;
• Frequency of invoking the warranty (order of magnitude); and
• DOT experience with pavement warranties (i.e., is the pavement better using warranties and does it cost more or less).

Information will be gathered through literature review, survey of DOTs, collection of relevant sample documents, and follow up interviews with selected agencies for the development of case examples. The synthesis will identify knowledge gaps and suggest research to address those gaps.
