Commission authorizes asphalt rejuvenation pilot after staff cites MnDOT study and $85,800 low bid
Summary
The commission authorized a pilot spray-on asphalt rejuvenation project (project 2300And7) with a recommended low bid of $85,800. Staff said MnDOT testing and other cities' experience indicate the product can extend pavement life by about five years.
City engineering staff presented a proposal to pilot a spray-on asphalt rejuvenation treatment as a lower-cost alternative to conventional chip seal. Dan Hansen said staff obtained multiple bids, with the lowest quoted amount at $85,800 and the highest at $173,774.20, and cited a Minnesota Department of Transportation three-year field study showing that selected rejuvenators slowed asphalt aging.
"The lowest bid was in the amount of $85,800," Hansen said, noting that other jurisdictions including Woodbury and Medford, Ore., have used similar products. Commissioners asked about winter slipperiness and whether the work could be self-performed. Hansen said the treatment can be applied from a truck-mounted applicator and that the city will hire a contractor for the first year to learn application techniques; competitive-bid thresholds would guide any decision to purchase equipment for in-house work. The motion to accept the low bid and authorize staff to proceed passed on a roll call vote.
