Abstract: A CRCP repair system is provided. The repair system may comprise a precast pavement panel having one or more openings positioned in the bottom, side portions thereof, as well as reinforcing members embedded within the panel. The panel may also include a reinforcing fastening member extending into each of the openings. The repair system may further include a prepared side edge of the CRCP having reinforcing anchoring members epoxy cemented therein and extending therefrom, with the anchoring members configured to extend into the openings of the panel with the panel positioned in the void created by the removed CRCP. The anchoring members may be configured in a pair, with each pair positioned to extend into the opening, with the fastening member extending into the opening between the pair of anchoring members.

Abstract: The described leveling lifter includes an engagement part embedded in a concrete slab, wherein the engagement part extends down to the base and contains a coupler component. The lifter may also include an actuator that is structured to engage the coupler within the concrete slab. The lifter also has a base configured under the engagement part. The base is configured to releasably couple to the concrete slab by projections set at a distance from one another on the base, the projections being configured to detach from the concrete slab in degrees upon engagement of the base by the actuator.

Abstract: A pre-fabricated pavement slab installation and replacement system is provided. The system includes a connector having an axial opening therethrough and engagement surface within the opening. The system further includes a pavement slab and an adjacent pavement slab, wherein a portion of the connector is embedded in the pavement slab and a remaining portion of the connector is exposed. The adjacent pavement slab has an interconnection slot, that can cover the remaining portion of the exposed connector. The system further provides that under the condition that the pavement slab and the adjacent pavement slab are cut apart, the connector is cut into a first half and a second half, wherein the first half of the connector contains the first engagement component and the second half of the connector contains the second engagement component. The first half of the connector can be subsequently removed by engaging the engagement surface.
