Concrete Pan Reinforcement
Concrete Pan Reinforcement
(OP)
We are designing a large truck delivery parking lot re-paving project and are adding a 12' wide concrete pan to replace a small portion of the existing asphalt. The geotech pavement resurfacing options are: (1) 11" of asphalt on 12" stabilized subgrade or (2) an 11" concrete section with 12" SS. The Client has selected the asphalt section, and I'm assuming the concrete pan needs to meet the recommended concrete section. A few other items to note:
(1) I've typically designed 6" thick concrete pans and never spec'd reinforcement
(2) The typical DOT section is 6" thick and does not include reinforcement
(3) The geotech report does not mention the need for reinforcement, but they could consider this a responsibility of the civil/structural engineer
Would concrete reinforcement normally be included for this application (thicker section and heavy-truck traffic)?

RE: Concrete Pan Reinforcement
Yes, the trucks can twist and turn in any direction. Loading is more or less unpredictable. For situations like this we used a minimum design of 12" thick, 4000 psi concrete with #4 bars @ 12", each way, top and bottom. Depending on soil conditions, dowels at joints may be appropriate, too.

turning and so far so good. (and its easy to place).

You may want to re-evaluate the use of plastic fibres; they provide little added strength except in their control of bleed water.
