Checkered Plate for Vehicle Loading 1

I'm not sure you can get a thinner type checkered plate to work with concentrated wheel loads.
It behaves simply like a plain plate so two way plate bending (either hand analysis or FEM) would be required to check stresses ... and deflections might be huge I think.
...unless your plate is very very thick of course.

Why not use grating as the primary structure and simply cap it off with thinner plate?

I'd recommended using a combination of heavy duty grating overlaid with checker plate.

If you want to have a look at the feasibility of plate the do the calculations yourself. Roark's Formulas for Stress and Strain should be able to help. But you'll likely find yourself needing very thick plate to limit deflection and stresses.

I've generally done road plate calcs by hand. I would personally be using the design truck from S6 or the provincial amendments (some provinces build stronger than the CL-625), barring something more applicable (parkade code, maybe building code for certain things, municipal regs for local roadways, etc). Do you care about the chequered part or do you just want a solid top?

Your options are likely:

1. Road plate / Thick Steel Plate - Just take a thick plate, size it and call it a day
2. Same as 1, but with a traction paint applied or a chequered plate welded to the top
3. Grating with a plate welded to the top to stop stuff falling in (I have seen this called compound grating)
4. Plate with stiffeners underneath

I've done all of these at various points. They're fine.

As an aside, do any of the Canadian practitioners know if CSA S413 prescribes different vehicle loading than the 18/36/54kN in the NBCC?

No idea, but S413 is one of the ones on the CSA website that you can view for free if you're Canadian and have a free account on csagroup.org. I still haven't figured out what criteria are used to decide if something is free to read. I know that this one, the pipeline codes, the LNG facilities standard, a bunch of the nuclear standards, the electrical code and some OHS related stuff is at least.
