Ultra Thin Asphalt Overlays
Ultra-Thin HMA is applied with an asphalt paver and promptly compacted with a steel wheel roller. This treatment is ready for traffic almost immediately after compaction. Thin HMA overlays provide a new asphalt surface and prolong the pavement structure life. This thin (0.5 to 1.0 inch) surfacing provides the benefits of an asphalt surface at a low cost that helps maintenance dollars go farther. $35,400 per lane mile was the average price for this treatment for projects let in 2011.
