Generally you tell the guy what you want, and he gives you an
estimate. You want excavation, tell them. Not rocket science!


Since you don't have any idea what you need, ask an expert who has
seen your driveway and can tell you what you need.


And DO NOT POST FROM THE SPAM COMPANY web site!

First step would be to investigate why you need new asphalt. Has the old one
broken up due to some defect in the base? Failed at the edges due to lack of
kerb restraint?

A good company would provide a brief description with the quote.  A typical
spec for a new driveway (in the UK) would include the following. Asphal is
normally called Tarmac in the UK.

* Excavate to reduced depth of at least 200mm below finished level (350mm
below dpc) and cart all spoil to licensed, off-site tip.
* Excavate any soft spots in sub-grade as required and dispose.
* Supply, lay and compact minimum of 100mm of DTp1 crushed stone sub-base
material to falls and levels.
* Supply, lay and compact 50mm of 20mm dense base course bitmac, and 25mm of
6mm hardstone bitmac wearing course to falls and levels.
* Clear all site of debris and rubble on completion and make good.
* All Tarmac to comply with BS 4987

PS:

DTp1 is a UK Department of Transport standard for crushed stone. Best is
limestone but other materials such as recycled concrete can comply.

Subgrade/compaction/and curb side protection all are important....
If the grade is not up to compaction it may need excavation and re-done.
An experienced ashpalt man would know.
I do concrete.....and that is an issue.
