When they lay new concrete launch pads and the rest of the quarter-mile in asphalt do they use modern measuring devices like laser beams, etc? Because nearly every NHRA track seems to have bumps in one lane or the other, or the transition from the concrete to the asphalt.
Why do we live in an imperfect world? Most of the bumps racers complain about would be considered "glassy-smooth" if they were on a highway instead of a racetrack. It might be possible to build a 1,320-foot billiard table, but I doubt we'd be able to afford the price of admission.
Why do I have two testicles??
Ha ha...that's funny. We'll be racing at Dallas this year, come and say hello.So that when you wake up in a haze and accidentally put your thong on back-to-front you are still symmetrical when you look in the mirror!!

John,
The best equipment is generally used for the surface of such tracks. It straddles the surface to be poured with a device called a vibrating screed to insure the finished surface is as designed. Most of these screeds follow a beam for the distance of the pour and these surfaces can be finished to exacting standards. Then, once they have cured you can refer back to Buzzz's post because expansion/contraction, soil conditions, moisture or the lack of it along with other factors come into play and it's virtually impossible to make 300 feet remain perfectly level much less thousands of feet.
The Bruton Smith tracks with underground tunnels also are constantly effected with the growth/shrinkage of the tunnel beneath. Vegas can be a downright carnival-type ride certain times of the year. It's just Mother Nature doing her best work for everyone to see and be reminded who's really in charge?
