We may have similar needs in the Wellington Region at some stage.
By the Alaskan Department of Transportation and Public Facilities:
Paving in the winter isn’t ideal, but it’s also not impossible. Check out the replies to this post to see what we’re doing to make sure repairs to quake-damaged asphalt are properly compacted before they get too cold.
We will add chemicals to the asphalt to lower the temp at which it can be compacted, get the mix extra hot before we pave, place a thicker layer so it takes longer to cool, & tarp loads to keep them hot during transport.
We will use multiple large rollers to compact it quicker, use the closest plants available to cut down on haul times, minimize truck wait times, and pave continuously without stopping.
It’s harder to pave in the winter and it uses more resources, but when it needs to be done, we know how to do it right [it would be good if the KCDC knew how to pave roads properly — Eds]. Alaska’s contractors are experienced and they are dedicated to repairing the asphalt surfaces damaged by this quake.
