Abstract:
1. A method of removing and replacing a pavement slab, the method comprising: cutting between a pavement slab and an adjacent pavement slab, wherein the cutting cuts a hollow connector into first and second parts positioned in the pavement slab and the adjacent pavement slab, respectively; vertically removing the adjacent pavement slab from next to the pavement slab to expose the first part of the hollow connector in the pavement slab; removing the first part of the hollow connector from the pavement slab; installing a full-size connector in the place of the first part of the hollow connector that was removed from the pavement slab; removing the second part of the connector from the adjacent pavement slab; cleaning out the interconnection slot in the adjacent pavement slab; and replacing the adjacent pavement slab next to the pavement slab by vertically lowering the adjacent pavement slab next to the pavement slab until the interconnection slot in the adjacent pavement slab covers the full-size connector in the pavement slab.
