I am looking to cover the surface of a farm driveway which is currently concrete. The surface is undulating, on a slope and is breaking up in places.
I am trying to find out if a covering of self-binding gravel will remain in place on this surface or if will rapidly get washed away by rain and spread beyond the driveway by vehicle movements. Any advice would be much appreciated.

Thanks for the reply.
The page you put the link to seems to be about loose gravel, which I had already discounted for all the reasons given on that page, but the page seems also to suggest (near the bottom) that self-binding gravel IS an alternative solution. Or did I read it wrongly?
The page on self-binding gravel doesn't mention a concrete base so any further advice would be very helpful.

any kind of gravel self binding or otherwise needs to be on a flexible base
which concrete is not
possibly you could crush the existing concret and use that as a suitable sub base
i imagine you have some heavy vehicles using the road being a farm and all?

self binding gravel wont stick to concrete it will last 5 mins,
my local councill did a car park with it 2 years ago, 3 monthes ago it was redone with different material, also a kids play area with it, again redone, i would not recomend the stuff MSH

simeon from ronacrete will be along in a bit to recommend their overlya products, or if the concrete was sound you 'could' use resin bound/bonded gravel.
BUT
few things
resin bound bond might not be appropriate surface if you have lots of heavy plant and wagon movenments i.e tractors, milk tankers, feed deliveries etc
and you mention the concrete is op to spec as its cracking and undulating
we do farm tracks etc and most cases they are either concrete, asphalt or grit stone cobbles. or farm tracks can be done in mot or cheaper road plainings but required more maintenance and regular regrading, easy enough if you have a tractor etc.
you could reuse existing concrete, excavate crush and relay as subbase as mentioned. but self binding gravel wont hold up to big agri tyres etc
we have stone cobbles and regularly run our john deere, excavators, wagons, etc up it on a step drive.

Thanks for all the advice.
Just to clarify, in case it makes a difference, all the barns have now been moved up to the yard which has a separate entrance from the road so no heavy machinery or trucks come onto the drive any more.
The concrete is undulating for drainage purposes. The site is on a slope although the concrete is level overall. The undulations are in place to run the rainwater away from the house and out of the driveway.
The breaking up of the concrete in places is due to its age (30-40 years) and that it used to take heavy machinery. The only use now is just for domestic cars on a normal family basis.

Thought this was a paving site, as opposed to an English grammar site ??? ???
