Abstract
A prefabricated paving slab includes specialized combinations of substantially vertical passages and cavities to enable “drop in” installation. The paving slab may include retractable coupling rods aligned using spacers having seating surfaces and alignment surfaces. Cavities of the paving slab, each configured for receiving a coupling rod, preferably are arranged in orientation(s) and pattern(s) selected for receiving and transferring the stresses of loads travelling in a pre-determined direction.
