There
are three main types of 'tarmac'
surface;
Hand Laid Bitmac, for domestic
driveways, footpaths and other
small areas. Machine Laid Bitmac
for larger drives, forecourts
and roads.
Hot Rolled Asphalt (HRA) machine-laid
as a wearing course on public
roads.
Tarmac is suitable for areas
to be trafficked by vehicles,
such as drives and forecourts,
and can be used for paths, although
we are not overly keen on using
tarmac for garden paths.
The
wearing course (the uppermost
surface) can be 'coloured' by
using a coloured binder, often
with coloured aggregates, or
by incorporating coloured, coated
chippings into a HRA wearing
course.
