Bitumen is typically laid thinner.
Asphalt has better/more fillers/particles/mineral aggregates.
I'm pretty much in the same boat...
New home with garage and driveway that needs doing/re-doing.
So I've kind of been wrestling with the same topic for that last 6 months.
Only difference is my father-in-law (great man) is a gardener, so he expects at the very least my lawns are cut and the edges trimmed. LOL
Oh yes, one other small difference is my garage/caport combo is unfortunately much smaller.
