WEATHER LIMITATIONS
Halt work when weather conditions detrimentally affect the quality of
patching or bonding concrete. Apply epoxy resin materials only when the
contact surfaces are completely dry and if the atmospheric and surface
temperature ranges are suitable for the specified epoxy material. Follow
manufacturer's instructions for weather conditions and temperature ranges.
1.7
TRAFFIC CONTROL
Do not permit vehicular or heavy equipment traffic on the pavement in the
work area during the curing period. At the end of the curing period, light
local traffic may be permitted on the pavement if approved by the
Contracting Officer.
1.8
EQUIPMENT
Use a container recommended by the epoxy manufacturer as the mixing vessel.
Use a power drive (air or spark-proof) propeller type blade for mixing
except that hand mixing may be used for small batches. Use equipment
specified by epoxy manufacturer for field mixing of aggregates and epoxy
resin.
