Have 70 x 2.25m drive to make from main track to our house. Currently, it is made up of "gahorra" - a mixture of gravel/sand/stones common here in Spain. The rain has ruined it and it now looks like the Andes.
We think that a readymix concrete drive is the answer and estimate around 16 cu. metres - is that about right. The local practice is to use iron mesh as the base - sounds OK? Ought we to put in a gap say every 5metres to allow for expansion? We get to approx -3 in the winter at night and 45+ in the summer.
Helpful comments please.

yes all sounds about correct,if you are planning anything heavier than a car you may want to make the concrete thicker say 150 MM in which case you would need closer to 24 M3
mesh helps yes and expansion joints too
have you thought about a passing place? 70 m is a long reverse and 2 cars cannot pass on 2.25m

thats a big pour for a diy'er, i'd want at least 4 guys without having to manually move the concrete,
scrape off, stone up and compact sub base, create an edge either with a wooden shutter(or hire road forms) or some decretive edging then i'd section it into the size of the wagons your getting. so a 6m3 wagon you section off a 22mx2.25m section based on an average depth of 120mm allowing for dips etc in sub base = 5.94m3 then tamp that off while your waiting for next wagon.
if you use 12mm ply to separate the road into sections you can leave them then remove and fill with an expansion joint material.
if this isn't coherent i blame the fact i've been in bed all day with man flue, those soakings last week got me.
