Public Works is owned by the same company that owns Concrete Construction and The Concrete Producer magazines, so we've done lots of articles on preserving concrete pavement: thin whitetopping, ultra-thin whitetopping, roller-compacted concrete, polymer overlays.
I feel like asphalt's gotten short shrift as a result.
Then I found this excellent video on Nashville's use of thin asphalt overlays (ThinLays): milling up and replacing the top 1.5 inches. Would you opt for this if the pavement's been extensively crack-sealed, had numerous slurry seals, etc. Do you know? Does your agency do ThinLays? Why or why not?
