macadam to a depth of 60mm / 2.5 inches, but don't know if it is 10mm or 20mm stone size (assume it is 20mm based on your earlier post)what type of blacktop are you laying?
SMA is a german developed mastic asphalt , it was first used to resist the wear of studded tyres , studded tyres were then banned in 1975 but the good old Germans had seen that it performed better than conventional asphaltic type wearing courses and decided to go big time into it , its extremley durable, highly resistant to cracking , ravelling( tyres leaving little circles on the surface when you preform excessive turning ) and damage by moisture. It can easily be laid by hand ( though it would'nt be my favorite past time these days!!) and is not dependent on weather unlike HRA.Its black in colour , closed texture and its no gimmick.
HRA is expensive.Its weather dependant as regards temperature so really summertime is the best time to lay , its probably not the best surface for a domestic job as there is a lot of attendant plant to place it, sometimes you see different coloured chips laid thru it eg red / white again v expensive, v,v durable , closed texture , again colour is usually black but if you got the cash any colour you want! again its no gimmick.
Macadam is what most smaller contractors lay and what most people end up lifting after 5-6 years cos it just looks s**t.
10mm macadam should only be used where no vehicular traffic will be present i.e footpath, 20mm macadam should be used on trafficed areas,
as a general rule the thickness of macadam to be laid should be a minimum of twice the maximum stone size , ideally 3 times i find is best.
EG 20mm macadam should be laid to a min depth of 60 mm or 2 1/2 " approx, again macadam is easily laid by hand but its quality is suspect as there are a lot of cowboys mixing it up in yards thruout the country.
As regards colour loss this is an unavoidable fact , mainly due to our wonderful Irish climate, amount of bitumen used and traffic volumes.
Better get back to work now , thats the most thinking i've done all day !!!
hope its some help to somebody.

can tarmacadam be laid directly on an existing concrete slab
