thank-you JLoomis!
We have finished concrete for over twenty years,my husband and i,
always the question, will you garauntee it won't crack. always the
answer....nope, gaaruntee it will!!
as for asphalt, as was said, adequate sub-grade prep is the key.
didn't you say that the contractor had driven on the concrete slab?
did they drive on the asphalt too, which you can as opposed to
concrete, but i believe 24 hrs is the time frame, depending on the
weather. did they compact the sub-grade? have you searched on-line for
answers anywhere else? and i have never seen a control joint in
asphalt, different type of material, different application. think of
all the parking lots youv'e seen.
rose, and yes, i am a female finisher!!
