FAQs > How soon can traffic go on cement-stabilized bases?
How soon can a newly constructed cement-stabilized
roadway base—whether a cement-treated base (CTB) or a full-depth
reclamation (FDR) base—be opened to traffic?
A properly constructed cement-stabilized roadway
base is one in which the roadway materials are homogenously blended
with the designed amount of portland cement and water, and then
compacted, graded, finished, and cured through the application of
a bituminous compound, a sealing membrane, or kept continuously
moist for a period of seven days.
 Completed
portions of these cement-stabilized bases can be opened immediately
to low-speed local traffic and to construction equipment, provided
the curing material or moist curing operations are not impaired,
and provided the cement-stabilized base is sufficiently stable to
withstand marring or permanent deformation. The section can be opened
up to all traffic after the cement-stabilized base has received
the curing compound or subsequent bituminous or concrete surfacing
and is sufficiently stable to withstand marring or permanent deformation.
If continuous moist curing is employed in lieu of a curing compound
or subsequent surfacing within seven days, the cement-stabilized
base can be opened to all traffic after the 7-day moist curing period,
provided the cement-stabilized base has hardened sufficiently to
prevent marring or permanent deformation.
