reinforcing steel for parking lot pavements

[abih]

By referring to formula 2-2 of ACI 330R-01 Guide for Design and Construction of Concrete Parking Lots, I receive 0.06 sq inch for a 5 in thick parking pavement. So my question is, do you really need reinforcing steel? Experience always say "properly designed reinforcement should be implemented" though. Any comments? Thanks.

No. Light duty pavements generally do not need reinforcing steel. Provide proper crack control and load transfer.
