Abstract
A semirigid floating pavement formed out of masses of reinforced concrete molded pieces, disposed side by side to form as wide a surface as needed. Each piece has a regular polygon plane with a flat top surface and an inner recess connected with the surface by means of a perforation and opening at its base. This base has the surface inclined toward the geometric center. Pieces are bedded onto a layer of sand. The inner recess is occupied with a mass of sand injected through the perforation which connects with the upper part, which perforation is closed up with an elastic cap or stopper. A channel is disposed around each piece in which is housed a joint acting as union and support between adjacent pieces.
