  • Publication number: 20010041092
    Abstract: A method and system for forming asphalt paving blocks for paving roadways, and the paving blocks used for paving roadways. The method comprises mixing asphalt in a stationary mixer, molding it into block-like paving elements, transporting the elements to a construction site and laying the elements to form a roadway. The system for forming the paving blocks comprises a molding press mounted on a trailer connected to a tractor, and storage shelves for storing pallets containing the molded paving elements. The paving elements are plastic-coated asphalt block-like elements. The paving elements have all the advantages of a traditional asphalt surface in terms of noise, but can be produced year-round and away from the construction site.

  • Patent number: 4787812
    Abstract: A self-propelled apparatus for lifting arrays of paving stones has a mobile arm one end of which carries a support for a polygonal assembly of suction cups having axially and angularly movable bellows which attract the paving stones of an array during transport. The support further carries directional jaws which are adjacent to the sides of the polygonal assembly of suction cups and are movable relative to the support to rearrange the paving stones of an array if the distribution of paving stones departs from an optimum distribution. The jaws are moved out of the way before the suction cups deposit the paving stones of an array so that a freshly deposited array can be placed into immediate or close proximity of the previously deposited array or arrays.
