For the first time since 1995, the track at Road America has fresh pavement.
Milling and grinding the entire 4.048-mile racetrack, including the pit lane, began on October 3.
Fine grading, a new base layer, and a new final surface asphalt layer followed in late October.
Now the all-new race surface has the entire off-season to cure before the 2023 season.
Engineers and Road America worked collaboratively throughout the project to improve drainage around the property and upgrade features that cross beneath the racing surface before paving.
This included increasing the size of culverts and running new conduits under the track to support the facility’s events.
