Thanks to Mr G Brown I have plenty of spare time on my hands so I am setting about converting the front garden to block paving. The drive is already done. The garden is dug out and I have used bricks from a demolished wall and broken concrete from the old foundations of a greenhouse as the hardcore for the paving. Problem is what is the best medium to crush down into the voids between the concrete. MOT looks as though it is too course for this so what should I use?

Did you get planning permission??? Also thanks to Mr Brown.
If its limestone MOT, just keep running a car over it until it isn't ;-)
Not yet but I am putting a soak away in.

Or just do it like I did 5 square meters do it, take photo then leave it a few weeks then another 5 square meters. Then leave it another couple of months and another 5 square meters :)

Have a look here
Don't do what I did and use a very weak sand/cement mix. The bloody stuff is too soft and the rats are digging tunnels under my paving. They are just wide enough for the blocks to fall in when you step on them.
Unless your concrete/brick is at least 200mm (8 inches) below the desired finish level, they'll have to come out, or get mashed up with something hefty.
If the gaps are too small for MOT the bulky stuff will have to come out, because it needs to be flat and you can't get it flat with big lumps, they will rock and you can't pack them down properly, IE mechanically - you need a whacker, or if it's going to get driven over, a vibrating roller, and you compact everything, add a layer of MOT, compact again, add another layer, compact again until you reach the desired height, then you trammel out a
50mm bed of gritsand so that it is perfectly flat and lay each block on top, and then whack over the blocks to push them down evenly into the gritsand (I'm looking in denis's direction here, Re; the rat situation), the gritsand becomes so compacted that nothing can get through it.
Type 1 MoT is the stuff to use. Well compacted with a plate vibrator it makes an ideal sub base.
