In the early 1990s the Indiana Department of Transportation (INDOT) developed a five-year warranty specification for asphalt pavements with the first project being built in 1996. In 2004, results indicated that the asphalt pavements built with the warranty specification had improved performance over the conventional asphalt pavements.Nineteen years have passed since the original asphalt pavement warranty project was placed in Indiana. It has been eleven years since the performance of the warranted asphalt pavements has been analyzed to determine the effectiveness of warranties. Therefore, it is prudent to reexamine the potential benefits of asphalt pavement warranties. Hence, the ultimate goal of the project is to advise the INDOT on whether the use of asphalt pavement warranties has potential benefit for lowering the cost of ownership for asphalt paved roadways.Overall, performance comparisons of Indiana's warranted and non-warranted asphalt pavements indicate that warranted asphalt pavements tend to perform more effectively than do non-warranted asphalt pavements. On average, warranted asphalt pavement sections had lower IRI values and rut depths than did non-warranted sections. The variability in IRI values and rut depths was also found to be less for warranted pavement sections than for the non-warranted sections. In terms of service life based on changes in IRI and rut depth, analyses indicate that warranted asphalt pavements could last 10 to 14 years longer than non-warranted asphalt pavements. When both initial capital costs and maintenance expenditures are considered, warranted asphalt pavements appear to be 15 to 40% more cost effective over a 5-year (short-term) period and 47 to 61% more cost effective over a 15-year (long-term) period. These savings do not include potential benefits of reduced user costs nor reduced INDOT inspection costs.

The performance warranty system is quite innovative in requiring a contractor's warranty for pavement performance over a certain period of time. European countries adopted performance warranty systems about 40 years ago. The United States adopted this system in the early 1990s to improve construction quality and performance, as well as to reduce life cycle cost. In Korea, for the purpose of resolving construction management and quality control problems and poor construction, the performance warranty system is considered as part of the solution. The appropriate performance indicators, reasonable threshold values, and warranty periods have to be selected in order to adopt a performance warranty system that requires keeping the pavement performance above a certain level of satisfaction for the warranty period. For this reason, structural, functional, and safety performance were defined first, and then rut depth, roughness, and crack ratio were selected as performance warranty indicators. For the purpose of suggesting performance warranty threshold values that reflect domestic circumstances, pavement management system data were surveyed, a special project was conducted, and a total of 888 sample sections were analyzed. A threshold level at 95 % of each indicator's distress was determined for the threshold value; this prevents the worst 5 % of poor performance cases. A 14-mm rut depth, 3.6 m/km International Roughness Index, and 20 % crack ratio for five years were selected as threshold values. To avoid early deterioration of pavement, three- to five-year warranty periods are suggested.

This synthesis on the use of warranties in road construction will be of interest to administrators, engineers, designers, and contractors involved with highway design and construction and the procurement process for these services. Experiences with use of warranties in Europe and the United States are cited and the potential impacts, benefits, and concerns of using warranties in the United States are identified. Actions needed to facilitate the use of warranties for highway projects in the United States are also discussed. The use of warranties in road construction is relatively widespread in the European highway industry compared to practice in the United States, where use has been limited. This report of the Transportation Research Board describes the various methods used in Europe for highway industry warranties and identifies the issues that need to be addressed before construction warranties can be translated to U.S. practice. Recent congressional proposals call for the use of warranties to be allowed on federal-aid highway projects. This has caused varied reactions from the parties involved in the design and construction of highways, resulting in a General Accounting Office study on methods for improving the quality of federal-aid highways, including the use of warranties. Ultimately, the owner will have to decide whether to use warranties in highway construction projects. Some of the potential benefits and concerns of using warranties, plus needed actions for successful implementation are presented in this synthesis, which is considered a snapshot of the issues at the time of publication.
