The normal progression of cracking initially occurs at intervals of 40 to 80 feet and then progresses to 18 to 20 feet.
WebJan 21, 2024 · Concrete pavement thicknesses should be rounded to the nearest 0.5 inch (10 mm) increment. Adequate concrete cover is needed to transfer stresses between the concrete and the dowel bars. Because of the required concrete cover, the minimum thickness of concrete pavement is 8 inches (200 mm). http://overlays.acpa.org/Concrete_Pavement/Technical/FATQ/Construction/Cracking.asp
