KINGMAN - Road crews from FNF Construction finished initial repaving work on a 10-mile stretch of Interstate 40 through Kingman this month, and they are set to return in mid-March to add the finishing touch, a layer of rubberized asphalt.
Crews hoped to lay the asphalt sooner, but were delayed due to decreasing temperatures throughout the area, which would hamper their ability to lay down the specialized material. Rubberized asphalt can only be applied at a certain heat level in order to assure it adheres properly to the existing surface.
Once crews return in March, Arizona Department of Transportation spokeswoman Michele Beggs said they should remain for about two weeks, with additional rolling lane and ramp closures scheduled for that period in both directions along I-40.
"It's not going to be for the duration that the previous work was," Beggs said. "It'll be a shorter time frame for the lane closures, and we'll try to expedite things as quickly as possible to provide the least amount of inconvenience to motorists."
While all the paving for this year has been completed, Beggs said crews are still out installing new guardrails along the highway, which will require additional lane closures through December. Following that, the highway should be clear for the next three months prior to installation of the rubberized asphalt.
A mixture of concrete and ground-up rubber, rubberized asphalt is a long-lasting, durable pavement material that reduces overall maintenance costs and has been shown to decrease road noise by up to 12 decibels. Once the asphalt is installed, Beggs said the most immediate effect motorists will notice will likely be a marked increase in the smoothness of their ride.
