HI,
I'm building a couple of concrete ramps for a creek bridge I put together last year. It's designed to support a riding mower and operator. The ramps will be 7' W x 10' L. I plan on compacting gravel and sand over the crushed stone and using 2" concrete chairs with wire mesh to strengthen the concrete.
I was wondering how deep the amount of base material I should use and the recommended thickness of the concrete itself. Also, if I should build concrete pads for support and stability and if so what specs should I be looking at and how to connect them to the ramps themselves.
Thanks.

why not just lower the bdge ? would work well IF it has decent supports

why sand ? it doesn't compact :no: couple inches of #57 stone over the goonies & place 4 1/2" of conc,,, that allows for #4 rebar,,, wire mesh is a pita as it should be placed 2 vertical midpoint =/- 5% or .2" iirc

Lowering the bridge is not an option. Four of the 6x6's are resting on concrete piers. But I was wondering if the ends of the ramps will require concrete pads to rest on.
