Apple tart and custard? I hope you ain't doing the work for someone cos you clearly don't know what you are doing. Are you a 'rip off merchant' by any chance? See you on TV.

You need a good base of hardcore with a sub-base of dolomite on top. For a car, you need the base to be around 25 to 35cm. Anything less will be too weak and the tarmac will soon start breaking up. It's extremely important to compress the base and level it before putting the tarmac down, otherwise as the loose base sinks in places, the tarmac will break up.

There is a material called crush and run which is pulverized gravel which includes fines or powdered gravel. Place it down first, spread evenly, compact it to a firm base and tarmac over. The crush and run will compact almost as firm as concrete. Check with demolition recyclers in your area because there is a product called crushed concrete which is the same consistancy as crush and run but cheaper. Be sure to spread evenly and compact the material. Spraying a bit of water on it while compacting helps set it. Good Luck!

Large Chippings - 10 or 20 mm in diameter. And then tarmac on top - the stones are a maximum of 5 mm.
A few people have mentioned a product called 'Crush & Run', but Dad who has worked in road surfacing/maintenance for nearly 4 decades has NEVER heard of it.

I would always err on the side of caution. A good 8inch sub base of compacted scalpings (hardcore) will be a good surface on which to tarmac.
Make sure it is compacted well using a vibrator plate (available from any hire shop for around £25-£50.)
Have fun

if the tarmac is for walking on only large lime stone and then small on top, finish with sand and hot roll tarmac is the best to put down.
if it is for a car to go on lime stone large and small and whacker plate down then a layer of concrete to firm the buildup and then hot roll on top.

There`s a material called crush & run, which is a mixture of gravel, sand, & I think granite dust. Or you could just put the granite dust, which is what I believe they use under concrete pads. It tamps down very evenly & solidly.
