Pavement Manual: Determining Concrete Pavement Thickness

For CPCD design, the computed concrete slab thickness should be rounded to the nearest full or half inch. For example, use slab thickness of 11.5 in. for computed thickness of 11.4 in., and use slab thickness of 10 in. for computed thickness of 10.24 in. The minimum slab thickness for CPCD is 6 in., and the maximum thickness is 12 in.
