Abstract: An apparatus for regenerating used mixtures for road pavement including an asphalt concrete mixture and a cement concrete mixture is provided with a first vibration sieve, conveyer, passage, roof, transferring means, guide means such as a V-shape plate and a screw conveyer, spray means such as water supply pipes, discharging means such as a hoist device, and a second vibration sieve. The asphalt concrete mixture together with others are sorted by the first vibration sieve, transferred in a given direction by the transferring means such as a container, heated by the hot water from the spray means, subdivided and sorted by the second vibration sieve.

Abstract: An asphalt regenerating apparatus including a drum in which blade means is provided and hot water is contained is disclosed. The asphalt waste is introduced into the drum and heated by the hot water contained in the drum. By revolving the blade means, the heated asphalt waste is subdivided, thereby becoming aggregate particles each having the surface coated with a thin asphalt film.

Abstract: Steam is injected into water to regenerate asphalt waste which is heated in the water to a predetermined temperature. Such heated asphalt waste is mechanically subdivided in the water into aggregate grains each having its surface coated with a thin asphalt film.
