Have a look on Gumtree or something similar for the tail end of someone's driveway project,
and put them on a line of block pavers,
with a dampproof membrane, between, it you want an A1 job.
Any weight on gravel will just compress the gravel into the soil,
unless you have a roll of geotextile, TS 45800, to separate the gravel from the soil.
It is an idea to line the soil inside the sleepers with the geotextile to prevent
pernicious weeds emerging in the future.
Other suppliers for these items are available, I just happened to have the Toolstation catalogue to hand.
