Are race tracks made of asphalt?
Asphalt for racetracks contains a polymer called styrene-butadiene-styrene (SBS), similar to what makes up Styrofoam cups. The asphalt must therefore be laid down at a higher temperature—about 320 degrees Fahrenheit versus 200 to 300 degrees for public highways. …

Only two NASCAR tracks are fully concrete. Commercial paving contractors and asphalt companies have worked with NASCAR and other racing Associations to develop blacktop that will resist the tremendous heat created by the high speed stock cars. While our highways seem to be similar, they are not.
Is concrete or asphalt better for traction?
Advantages of Asphalt Roads
New asphalt is quieter than concrete. Though it creates a smooth drive, it also boasts better traction and skid resistance.
How thick is a NASCAR track?
Track length – 1.33 mile tri-oval. Pavement thickness – 6” of Portland Cement Concrete Pavement. Designed to hold a seating capacity of 200,000 people.
Does concrete or asphalt have more grip?
Concrete gives a more consistent grip level than blacktop through the various temperature ranges we experience during a weekend as well,” Rick Campbell said.
Is racetrack different from tarmac?
Track surface is not a constant, and over the years the track can change as it ages. “As a track gets older, different things happen. For example, the colour of tarmac can often fade, so a new track is more black than an older surface, and the darker surface attracts heat from the sun more than a lighter surface.
