For Navy pavements, a neat bead of caulk may be applied as indicated to prevent
grout or concrete from by-passing filler and entering the joint space. For keyed joints,
an additional bead of caulk may be necessary to prevent grout or concrete from
entering keyed joint.
Repair personnel should apply and scrub cement grout bonding course on all exposed
cavity surfaces except faces of joints and working cracks. The cavity should be filled
with concrete flush with the pavement surface. Sand-cement grout bonding is not to be
used when a particular type of bonding agent is specified for a manufacturer's material
(for example, an epoxy bonding agent for an epoxy concrete).
