I had a section of a driveway replaced 16 years ago and still not a sign of
any cracks. It had fiber in it and no rebar. This is in Memphis. Perhaps it
is different in a colder climate.
Several years ago one of the do-it-yourself magazines recommended using both
rebar and fiber. As I recall they were saying the fibers prevented small
cracks which could develop into large cracks and the rebar was for support
against major cracks from heavy loads.

going to have a new driveway poured. One of the contractors [with the best
price] said we didn't need rebar because the concrete he used has the fiber
in it. Should I insist on rebar or does the fiber negate the need for
rebar?
TIA
