Abstract
Precast concrete paver blocks are provided with interlocking edge joints so that abutting edges of adjacent paver blocks align when the blocks are installed and are maintained in alignment. At each joint, each block includes a tapered projection and a recess. When edges of two blocks are moved to abut each other, the tapered joint projection on each block enters the joint recess on the other block. The taper on the projections move the blocks to align the block surfaces. The edges of the blocks are angled or relieved below the joints to ensure a tight fit at the top of the paver blocks.
