SMA is a thin coat asphalt, not really suitable to be laid in them thicknesses. It also needs to be laid on very good base course or it will break up. It tends to have a bit of a bad reputation in the industry, mainly as its been used in applications it was not designed for. As its thin coat, local authorities have used it on roads that really needed a more thorough reconstruction to cut costs as it goes further. End result on many occations was it did not last the course.
It is however very good laid in the right application and specification, and is widely used as a motorway top coat, where it preforms very well.
If its a straight run, and only a farm track, provided the sub layer is good, i would consider a layer of 20mm dense base 125 pen macadam, in hard stone if availabe. Also ask for a recipe mix as opposed to a design, they tend to have more bitumen in them.
Ideally this needs topping off with a surface coat to seal it, 10mm would give a good surface, but you could do this in a few years time to give it a second life as it were.
Or a cheap option to seal it would be to lay the base course and then surface dress it.

We have a concrete lane from the seventies that is needing redone. The top is blowing off it and it's getting rough, but it hasn't cracked and broken into plates or sections, so the bottom must be good. Traffic is a 50/50 mixture of cars and heavy tractor traffic. Would tarmac base be suitable to put on top of it? If so what does one ask for? Or do we need to hammer it up and reconcrete it? It's a busy lane and would be hard to keep traffic off for three weeks nowadays.
It's about 300m long, and there is an issue with water. Would need to add drainage points and camber.

I have heard of asphalt placed on concrete, but also seen a road that was done were the asphalt was lifting badly.
Two main issues will be creating a bond between the two materials, and the different rates at which both move and expand as the road surface temperature changes.
Better having a word with a reputable surfacing contractor to see what they think

We tarred over the top of the concrete base in 2 of our silage pits and they've been fine.

Ours are outdoors, when they did ours they ran a roller over the concrete first to make sure any lose bits came off then blew it all off with leaf blowers.
How long ago was it done? How well is lasting?

Is a base coat sufficient?
What depth and cost should I expect per 10x100m?

Get Tarmac to quote. You'll be surprised how competitive they are and it's done properly.

First one must be 10 years old, second one a year newer and they're holding up fine.

What spec of tarmac was used? Seems to be a few options and not sure which is best suited to silage clamps
