Abstract
Abstract A concrete paving slab formed of a number of individual spaced blocks connected together by drops of flexible synthetic resin adhesive. The adhesive drops are normally located midway between the top and bottom of the blocks and extend between the sides of the blocks. Recesses may be formed in the sides of the blocks, extending from the top part way down the sides, with the adhesive drops extending between the bottoms of the recesses, and cables may be laid in the joints and adhered to the adhesive. The composite slab can be handled and laid as a unit, and the joints filled with sand or mortar.
