It is likely the mix design for driveways is considerably different
then for highways. It may have smaller aggregate size and less
inherent strength from the aggregate making it more important for the

not going to be nearly as large and heavy so it will not be as well
compacted, which again makes it more important that the asphalt have
some time to set up.
