Concrete Slab Details for Steel Tracked Vehicles

[jdcpese]

Does anybody have industry references and/or standard details for concrete floor slabs subjected to steel-tracked vehicles? I have a copy of UFC 3-320-06a which recommends using 5000 psi concrete, but it does not discuss the topic beyond that. Is the increased concrete strength sufficient to prevent the floor from being torn up by turning vehicles or do steel plates need to be placed in the floor slab or is there better method for addressing this servicibility criterion? Thanks for your help.

Army Corps of Engineers must have some info on 'tracked vehicle repair facilities'.

Steel fibres are very beneficial in making concrete tougher against abrasion. Workshops for tracked vehicles typically employ steel fibre concrete.

My experience with this is that you will need to specify a heavy duty surface hardener. Or....one design I have used is to design a "sacrificial slab" which can be replaced when needed. I designed the main structural load bearing slab then used a heavy mil plastic as a bond breaker, then a 5" "sacrificial slab". Once the 5" slab is worn, it can be replaced. Of course the owner has to monitor the wear. If not, the operators will continue to wear into the structural slab. For my project, it was less expensive to do this and replace the slab in 5 years than to use the surface hardener.

For a garage servicing tracked vehicles, a buddy of mine suggested that I find some surplus rail from the railroad and embed these in the concrete such that over a period of years the concrete would only be fretted down to the steel. In addition, attachments can be welded to the rails and used to hold/pull components on heavy equipment. My friend work for Caterpillar in their heavy equipment repair shop as a foreman.

It might depend on what kind of tracks. Heavily cleated steel tracks for some 'dozers will tear up concrete in a hurry. But there are treads intended for use on roads, too - some (most?) tank treads have rubber pads to help them grip on concrete, and these tend to not shred the concrete. My Dad always laid down wood planks when crossing roadways with a dozer, or when rolling it into the shop.
