Making concrete last as loading area.

We are trying to see if there is a way to help our slab loading areas survive. We have waste piles that are stockpiled on slabs and loaded with large loaders with teeth. When I say large I’m talking letourneau 1350’s and bigger. The piles are very wet and often mud so just raising the bucket off the ground isn’t an option either. Smooth buckets isn’t really an option. So we have considered rails but afraid the concrete will crumble away between the rails and a tooth catch a rail. Any ideas?
