Hi folks,

need some help!

We are planning to resurface the drive down to the Scout Hut and we are
thinking of using road planings. So, how thick do they need to be, how
to we lay/compact them and will they be suitable for driving on?

Many thanks

Your best bet is not to consider them to be "surface" but just a cheap
aggregate. In warm weather with driving on they consolidate well but
they won't be like a tarmac road.
You need three or four inches for it to bind at all, otherwise it just
goes to pieces and mixes with whatever's there now.
There might be a few big bits need smashing up .

Absolute minimum 3", best case over 6". Best laid out with a wide
ditching bucket on a digger, then 'tracked in' using the diggers
tracks. Heavier digger the better and needs to have steel tracks not
rubber. When nice and compacted by the digger (many traverses both up
and down the track and side to side), then finish with a vibrating
roller. Twin roller is much easier to get a flat surface than with a
single. The naughty ones water the surface with red diesel before
using the roller, it softens the tar so the surface binds well, not
one for the environmentalists though.

I thought the tracks were there to lower the surface loading of the digger..
making the loading much lower than you get with a car on its four hand sized
tyre areas.
you would get more pressure using the back of the bucket than the tracks.

True, but if there's a bump, the full weight of the machine goes on it
so flattenning it out.

There are two sorts of track, smooth ones to reduce ground pressure
(eg 360 deg excavator) and ones with bars that cut into the ground/
embed for pushing machinery (eg a dozer)

Back of the bucket is the way to spread them arround, but belive me,
the steel tracks on a 22 ton digger are the best way to compact them
before rolling. The rear of the bucket tends to smear the planings,
moving then somewhat unlike the tracks that give a nice downwards
squash. Still need the roller mind. Don't bother using a light
digger - waste of time.
