PROTECTION OF PAVEMENT
**************************************************************************
NOTE: The basic requirement is to avoid traffic
damage to the PFC. The minimum suggested cure time
for PFCs on roads is 12 hours. The time
requirements can be shortened provided that no sharp
turning or stopping of the traffic on the PFC is
allowed. PFCs on airfield pavement require an
absolute minimum of 2 days to cure sufficiently to
be able to satisfactorily handle carefully
controlled aircraft traffic. Short or locked wheel
turns should never be permitted on the PFC.
**************************************************************************
After final rolling, no vehicular traffic of any kind shall be permitted on
the pavement for [_____] days.
