I am serving on the NCHRP Synthesis 20-05/50-09 on pavement warranties. It would be helpful for this project to know whom to send any survey to since this subject resides in different areas of different DOTs.
The following questions were asked as part of this survey:
1. Does your state do pavement warranties?
2. If so, who would be the right expert to answer questions about specifications, data collection, warranty enforcement, etc.?
