"COMPONENTS FOR BALLAST-LESS RAILROAD LINES LAID ON PRE-FABRICATED REINFORCED CONCRETE SLABS" ABSTRACT The invention is concerned with components for ballst-less railroad lines laid on pre-fabricated reinforced concrete slabs, which can eliminate the need for periodic maintenance of the ballast of traditional railroad lines, such maintenance being expensive and often difficult to carry out. The components include pre-fabricated, possibly pre- stressed, slabs positioned upon a steel reinforced concrete block having the functions of a foundation and connector for the pre-fabricated slabs, with the interposition of a concrete-asphalt mortar layer between the slabs and block; said slabs being secured to the foundation block either by means of two half- cylinders, forming parts of the slab structure, or of the bond formed by the upturned sides of the foundation block (tub).
