steel within the pavement, thickness design of CRCP is identical to
other rigid pavement types.
The advantages for placing steel in PCC pavements include:
1. Reducing the number of required joints between slabs, result-
ing in decreased maintenance costs
2. Prolonging service life when pavement is overloaded
3. Reducing pavement deflection
