I did not know about the road fabric, thanks!
Just for clarity, it is not washing around the culvert, the road bed (on 
the tire tread path) washes away to expose the culvert underneath. 
Thgat fabric might work there, too, and would be much lighter in weight 
than steel.  It would not distribute the weight, but it might hold the 
underlaying soil in place so that the surface gravel has a nice 'bed'.
Thanks Gloria-and it is good to 'see' you again!

Many of our greatest American thinkers, men of the caliber of Thomas 
Jefferson, Henry Thoreau, Mark Twain, William James, and John Muir, have 
found the forest an effective stimulus to original thought.
