• 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
