Any ideas or caveats please for glueing paper to hardboard?
I have an old Geographia street map (ca. 1960) which is failing by
splitting along the folds. It has been stuck together with Sellotape,
but even that's drying out. My idea is to glue the bits to a backing
of hardboard (30" x 40") and carefully tease out the dog-eared edges.
My concern is that if I was to use water-based adhesive, such as PVA,
the hardboard may swell and curl.
Possibly 3M spray photo adhesive?
Not exactly answering your question but: you used to be able to get a pot of 'map preserver', which purported to make maps more resilient to tearingetc. at the folds. IIRC correctly it came in white pots, and you (probably) painted it over the map, especially the seams. I don't remember the product name, I afraid, but this might be a useful precursor to attempting to pasted it down.
As for the actual pasting down, I'd probably try wallpaper paste, and experiment of a scrap piece of hardboard first.
Sellotape is a very poor choice for paper seam repair, BTW. You need proper book repair tape.

 Just recovering from my 5th blown fuse in the old brainbox 9stroke0
and the memory is a little shaky at the moment.
I wonder if hardboard is perhaps not the best material for a backing.
Display photographs are mounted onto a much lighter (but equally) rigid
foam-based board which is presumably designed to accept spray mount adhesive
without distorting. You might be better off with something like that.
A lot depends on whether the map has any sort of value or you just want
to keep it while longer but hardboard is not a good substrate for
long-term conservation, nor is wallpaper paste a great idea.
Have a look at a good picture frame suppliers, like Lion
They sell museum quality boards and adhesives (at a price). Nominally
trade only and they have a minimum order by post but if you are near to
one of their depots Ive never been turned away
