• Abstract:
  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
