EXECUTION
3.1
PREPARATION
3.1.1
Epoxy Concrete
3.1.1.1
Patch Areas
Remove loose concrete from the spalled areas indicated. Inspect the cavity
for remaining defective concrete by tapping with a hammer or steel rod and
listening for dull or hollow sounds. In areas where tapping does not
produce a solid tone, remove additional concrete until testing produces a
solid tone. Make the entire cavity at least 25 mm one inch deep. Sawcut
edges of cavity to avoid feather edging. Prepare surface of cavity by
sandblasting, grinding, or water blasting. Remove dust, dirt, and loosely
bonded material resulting from cleaning. Ensure cavity surfaces are dry.
3.1.1.2
Spalls at Joints and Cracks
**************************************************************************
NOTE: Use this paragraph when repairing pavements.
**************************************************************************
For spalls to be repaired that are adjacent to joints and working cracks
insert preformed joint filler to the working faces of the spall. Trim
filler to fit shape of the working faces of joint or crack so epoxy
material is prevented from bypassing filler. Where practicable, extend
filler horizontally and vertically into joint or crack opening. Secure
filler strip in place prior to and during placement of epoxy concrete.
[Apply a bond breaker to working faces at keyed joints. Keep bond breaker
off of concrete surface to be bonded.] After the epoxy concrete has
completely cured, saw out the top 25 mm inch of the preformed joint filler
and install liquid joint sealer in accordance with Section [02760 FIELD
MOLDED SEALANTS FOR SEALING JOINTS IN RIGID PAVEMENTS][02762 COMPRESSION
JOINT SEALS FOR CONCRETE PAVEMENTS].
3.1.1.3
Joints and Cracks
**************************************************************************
NOTE: Use this paragraph when repairing pavements.
Fill in either Section 02762, "Joints,
Reinforcement, and Mooring Eyes in Concrete
Pavements" or Section 02982, "Resealing of Joints in
Rigid Pavement."
NOTE: Insert the appropriate Section number and
