“Concrete Floors on Ground” by
Ralph E. Spears, PCA 1978 or the updated version “Concrete Floors on
Ground”, EB075. Both have design charts for axles with single and
dual wheels. We did a slab design for the local fire department 4 or 5
years ago. I think it was 8” think with wire mesh. We made
sure the wire mesh was where it was suppose to be and wet cured the
concrete. Also, put control joints at 15’. I was there last
week and there are no cracks. It is holding up fine. But the PCA
design guide walks you through the design.

Don’t ask me why,
but I need to design a driveway (on grade) for a fire truck. I believe the
owner wants to use AC, but if he must go with PCC, then he will.
Are there any good
guidelines, references, methods used to design a section for this purpose? I
sure would hate to waste a bunch of time if this is something that is pretty
I’m supposed to be
receiving wheel loads later today.
