Repaving of the 2-mile oval scheduled to begin Aug. 22, the day after Cup race

BROOKLYN, Mich. -- Phase 1 of the Michigan International Speedway Track Repaving Project has been completed. The entire pit-road and drainage project took just 30 days to complete.

Here are a few highlights from Phase 1 of the track repave:

Pit-road repave: During and after

Drainage

A drainage trench was installed below the white line in the turns and on the frontstretch. This stone-filled trench will collect water trapped in the existing pavement and reduce the potential for water weeping out of the track surface.

Demolition

The existing pit road was removed by milling machines to a depth of 9 inches. The ground-up asphalt was stockpiled on-site. Discussions are under way to explore the potential for creating souvenirs from this historic material.

Paving

Local construction contractor, Ajax Paving Industries of Troy, Mich., was selected to perform the work. The Ajax resume includes paving parabolic test tracks for the Big 3 automakers and the current repaving of Phoenix International Raceway.

Once the existing asphalt was removed, a 4 inch aggregate base course was installed. Ajax then placed three layers of polymermodified asphalt on pit road. The bottom layer is a 2 inch-thick base course; the second layer is a 1.5 inch-thick leveling course; and the top layer is a 1.5 inch wearing course.

The new asphalt pavement had to match the edges of the existing concrete pit stalls on driver's left, and the existing curb and gutter on driver's right -- yet develop a smooth surface.

"What a tremendous effort by Ajax Paving to finish Phase 1 of the project in just 30 days," MIS president Roger Curtis said. "This gives us plenty of time to continue to utilize the facility for track rentals and get ready for the upcoming NASCAR Sprint Cup Series Pure Michigan 400 race weekend on Aug. 19-21. Now, the focus shifts to repaving the oval, which is obviously the bigger of the two projects. We'll be ready to begin on Aug. 22, the day after the Pure Michigan 400."

A few projects remain before the Pure Michigan 400 race weekend. Crews will be busy striping pit road and grading and grassing apron areas during the next couple of weeks.

"We were very pleased with the work and have just a few small projects to finish. Everything went very smoothly and now we look forward to beginning the oval after the Pure Michigan 400 race," Ajax Paving director of corporate development Fred Hillard Jr. said. "Everything was completed on schedule and we've enjoyed working with MIS and their parent company, ISC, on this project. Repaving the oval will be memorable for our group because we are based right here in Michigan."

This is the first repave MIS has received since 1995 and just the fourth time overall. The track was built in 1968. The track was repaved in 1977, 1986 and 1995.
