  • Patent number: 10619314
    Abstract: An apparatus for in-place recycling of materials that form part of a roadway pavement with agglomerated aggregates in a bituminous composition, includes a load-bearing structure suitable for driving on the pavement in a direction of travel and carries, from the front to the rear in the direction of travel, a transverse milling machine for milling the pavement to a defined depth and width to produce milling debris, a mixing device for mixing the milling debris with a binding composition, and a spreading sub-assembly for distributing the milling debris/binding composition mixture across the milled pavement. The apparatus further includes a crusher with blades, between the milling machine and the mixing device, open on the bottom, for crushing the milling debris. In one embodiment, the crusher and the mixing device are located in a single unit. The application also relates to a crusher for milling debris from roadway pavements.
