- Break out and remove the old surface and spoil
- Dig to formation level, usually around 230–250 mm below finished height
- 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
- Surface course (AC 6 dense), about 20–30 mm, laid hot and rolled
