What is included?

A new tarmac driveway is built from the ground up: the old surface and soil are dug out, a compacted stone sub-base is laid, then a hot binder course and a finer surface course are spread and rolled, and the edges are held by kerbs or blocks.

Dig to formation level, usually around 230–250 mm below finished height
Geotextile membrane where the ground is soft or clay
MOT Type 1 sub-base laid and compacted in layers, about 150 mm
Concrete-haunched kerbs or a block-paved border as edge restraint
Binder course (AC 20 dense), about 50–60 mm, laid hot and rolled
Falls set so water runs to a channel, gully or soft landscaping

In Northern Ireland, more than 5 m² of hard surface in front of a house should be porous or drain to a porous area within the property; DfI Roads approves dropped kerbs. If the job needs a dropped kerb, DfI Roads approves it before any work on the footway.
