The resurfacing of Charlotte Motor Speedway marks the third time the entire 1.5-mile oval has been repaved since the track opened in 1960. The first new layer of asphalt was applied in 1973 and the most recent repaving came prior to the 1994 season. In between the track's corners received fresh coats of asphalt in 1979 and 1987.
Charlotte Motor Speedway resurfacing fast facts:
Including design, surveying, safer barrier removal and re-installation, track milling, repairs to the concrete retaining walls and paving, officials estimate the resurfacing project will require 25,000 to 30,000 man hours.
In excess of 10,000 tons (20 million pounds) of asphalt will be used to coat the racing surface from the white line to the outside retaining wall.
That's equivalent to the weight of 5,882 NASCAR NEXTEL Cup cars. If placed bumper to bumper, those 5,882 cars would circle the 1.5-mile track 12.5 times.
The repaving of the racing surface will be done in two layers using a special polymer in the asphalt mix. The first layer will be 2 inches in depth and the final layer of asphalt will be 1.5 inches thick.
An additional 4,000 to 6,000 tons of asphalt will be used to resurface the aprons, pit road and the turns of the frontstretch quarter-mile oval.
To ensure a smooth racing surface, engineers utilized three-dimensional digital surveying techniques, technology not available when the track was built in 1960 or last repaved in 1994.

Sunmount is the industry leader in resurfacing high-banked race tracks and its resume includes six high-profile facilities including Atlanta Motor Speedway and Texas Motor Speedway.
