Well, it isn't really gravel. It's limestone, mostly one inch lumps. The
limestone is a couple of inches deep, then there's six to nine inches of
rubble underneath. There's 187 sq metres. In places moss has grown. I've
killed the moss but under it the stone has a lot of soil mixed in,
somehow. I'll have to scrape all this off and put new stone down, but
how can I stop this happening again? I was wondering about waiting until
the dry weather and getting some sort of blow torch thing? Ideas?

You can't really "stop this happening again", gravel (or similar)
drives need maintenance and 'stuff like soil' will always build up
over time.

Our gravel drive has become easier to keep weed free as it has become
more compacted (which does need fine material, whether sand or soil)
but, especially around the edges where it is still looser it needs
fairly regular weed killing.
