Concrete degradation is common on race tracks around the country, northern tracks have the worse issues with freeze/thaw cycle.

Normally, the degradation begins at control joints. A combination of water freeze/thaw cycle, tire dragging, scraping rubber, high power traction compounds all work to destroy your concrete.

Think about it: when you're proud of that track and you can barely walk on it, just think of the force a soft race slick puts on the chemically enhanced surface, trying to constantly rip the concrete aggregates out. We haven’t even talked downforce... a Top Fuel car puts out an estimated 8,000 lbs. of downforce and Pro Mods are in the 3,000 lbs. area. These factors all take their toll on the concrete’s life!
