Thickness Slab on-grade for haul trucks
Thickness Slab on-grade for haul trucks
(OP)
Currently I'm looking for info on designing a concrete slab on grade.
The slab will have dimension of 35ft by 20ft, and will be sitting on compacted soil. The slab requires to be able to handle loaded haul trucks of an aproximate 800 tons.
Can somebody help me with the steps on how to find the required thickness of the slab.
Thanks

here's the UFC(NAVFAC) link i fall back on pretty regularly since the info is reliable and is fairly straight-forward reading most of the time.
h
in particular, see "UFC 3-250-12N Design: Pavements". there's a few other references on that link that get a little more in to the nuts and bolts of it all.
to tackle pavement design, i typically like to know the anticipated subgrade conditions, EALs, traffic type (tractor trailers and what configuration, forklift, box truck, etc), turning conditions, driving lanes, life/performance expectancy, etc. it can get pretty in depth at times. for your situation, i would think that it would be more cost effective to pull a safe number out of the air based on the surrounding conditions (i assume that there's pavement of some sort around/leading up to your 35x20 area). for example, if there's asphaltic concrete leading up to this concrete area and the ac pavement is 4" base course and 2" ac, then 8" of concrete should be well to the safe side (unless this happens to be a dumpster pad which could be an entirely different animal to deal with).
hopefully, my ramblings will help. good luck.

You driving these Leibherr (sp) trucks? They make them down the road from me in Virginia and they're HUGE!

The most economical approach is to over-do the slab thinkness since the incremental thickness cost is so minimal in comparison to the long term benfits of rigidity. Then you are just left with the soil/base properties and any transitions to other sections of access.
I assume this slab is contiguous with a scale, crusher or dumphouse with significant foundations below grade.
