asphalt/black top requires a machine to lay it HOT
For an area the size of a carport....no mechanized spreaders would be used... even the smallest shoulder machine would be barely able to spread hot-mix in the few feet it could travel...

A small space like a carport would be all handwork... a bunch of guy shoveling a pile of hot mix dumped in entrance, then shoveled and raked to grade, and finally screeded with an 8-10' strait edge (maybe)...

Finally it would be compacted with plate tamper, and small walk behind double drum rollers...

Asphalt is the wrong choice for this application.... as mentioned previously.... jack stands impressing on the asphalt.... etc..

Got a quote today of 105.00 a yard and it will take 3 yards. That's 3,000 lb. with glass reinforcement and it will be about 6 " thick. The contractor said it would easily hold up to my 2500 lb. truck camper. This is probably the way I will go. To be extra safe I'll put in some rebar every 2 ' in both directions should last my lifetime and then some.
Concrete is the better choice...Big time contractors pay about $110 cy/yd here in greater NY for "State approved mix", so $105 in situ seems reasonable...

Also since this is a fiber reinforced mix, I think you would be better served by using some WWM (welded wire mesh) instead of

just putting rebar in a slab randomly might make you feel good.... but it might really just be a wasted effort and expense....

Finally, try and impress on the guy running the placement... that the concrete should not be"blessed" with a guy flinging water on the surface that makes it easier to finish.... That extra water they apply will be a problem down the road...

And Finally, finally.... keep the slab wet for at least 7 days from when it was placed......just needs to be wet, not a deluge of water.... wet.. opaque plastic on top and a soaker hose just barely on.. sort of wet..
