Jabrock was or is also the name of a fabric reinforced plastic composite
which was used in the aircraft industry for jigs & tooling at the time of
the Vickers Vicount aircraft.

Jabrock is a hard wood grown in the Philippines.
Not too common now as so much of all woods there have been depleted.
Lignum is, I believe, from a south American tree.
As for wood for roads, I once came across the amount of wear on wooden roads
in London, and added it to my website as the sort of trivia that might
interest someone.

I have been interested in the discussions about Jarrah because my father,
(who was an aircraft fitter in the 1940s) occaisionaly brought home blocks
of a
material which he called Jabrock.
This material was made up of wooden laminations each about 1/16 inch thick
and appeared to be available in thicknesses up to about 3 inches. It was
very
hard and surprisingly heavy for a product used in aircraft. Could this have
been
made from Jarrah?.
Another thing which has always intriged me is - what does a lignum vitea
tree
look like?.
