Whether it's granite or the local rock available, a similar short ramp, around 22" deep at its peak, has proven durable for nearly two decades with layered compaction. Check out the calculator for your concrete needs!

As you say things are still moving, rip the concrete ramp out and start again. DIG OUT to SUBSOIL. I think you will find the original ramp is on topsoil( think toothpaste foundation).
Weather you go timber or concrete I reccomend a 3" AIR GAP between the ramp and the building with a steel plate over the air gap.
Also make the ramp longer for greater ease of entry.
Good luck.

If there’s a steel mill nearby see if you can get slag its heavier than gravel and won move as easily due to rain.

it also packs tight.
