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.

Break out and remove the old surface and spoil
Dig to formation level, usually around 230–250 mm below finished height
Geotextile membrane where the ground is soft or clay
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

Rules in Cornwall

In England, a new hard surface over 5 m² in front of a house needs planning permission unless it is porous or drains to a lawn, border or soakaway within the property. Any new or widened crossing over the pavement needs approval from the highway authority (the county or unitary council).
