Michigan International Speedway will be repaved, track president Roger Curtis announced today with Bill Braniff, of International Speedway Corporation. After this weekend’s Heluva Good! Sour Cream Dips 400, pit road will be repaved. Then, after the August Sprint Cup race, the track will be repaved.
The repaving, which will cost about $7 million, will involve the removal of the top two inches of the track. This will allow the bumps to be smoothed out and will increase grip, and therefore speeds, at the track.
A laser survey revealed that the track has a hinge (progressive banking) in the corners that has made the racing here exciting due to several racing lines. That banking will not be affected by the repaving.
This is simply a repaving, the track will not be reconfigured.
