In an apparatus (G) for laying road pavement layers composed of first and second pavement material grades, there are provided at least one road finisher (F', F1, F2) comprising a material hopper, and a feeder (B) arranged upstream thereof and including a bulk material hopper (2) for the first pavement material grade (A) as well as a longitudinal conveying means (3, 4), wherein in the apparatus (G) the sole road finisher (F') comprises a second material hopper (29) for the second pavement material grade (B1) or a second road finisher comprising a material hopper (29') for the second pavement material grade (B1) is provided behind a first road finisher (F1), and the feeder (B) comprises a superstructure (6) extending above the bulk material hopper (2) and the first longitudinal conveying device (3, 4) and including a second longitudinal conveying and intermediate storage device (7, 10, 14) which extends either up to and over the second material hopper (29) of the sole road finisher (F') or the material hopper (29') of the rear road finisher (F2), a section (7) of the second longitudinal conveying and intermediate storage device being adjustable relative to the bulk material hopper (2) between a material receiving position and a passive position in which the bulk material hopper (2) is accessible to receive material.
In an apparatus for laying road-surface layers composed of first and second grades of pavement materials, comprising a first-road finisher having at a front side thereof a material hopper for receiving the first grade of pavement material and a feeder located upstream with respect to a traveling working direction of said first road finisher, said feeder comprising a movable substructure, a bulk material hopper located on said substructure for receiving said first grade of pavement material and a first longitudinal conveying device extending from said bulk material hopper up to and over the material hopper of said first road finisher for feeding said first grade of pavement material to said material hopper, the improvement comprising a second road finisher having a material hopper for receiving the second grade of pavement material located behind the first road finisher, a superstructure on said feeder that extends above the bulk material hopper and the first longitudinal conveying device, a second longitudinal conveying and intermediate storage device on said superstructure of said feeder for feeding the second grade of pavement material to the material hopper of the second road finisher, the second longitudinal conveying and intermediate storage device extending up to and over the material hopper of the second road finisher, and a forward section of the second longitudinal conveying and intermediate storage device being adjustable on said feeder relative to the bulk material hopper between a position for receiving the second grade of pavement material and a passive position in which the bulk material hopper of said feeder is accessible for receiving the first grade of pavement material.
In an apparatus for laying road-surface layers composed of first and second grades of pavement materials, comprising a road finisher having at a front side thereof a first material hopper for receiving the first grade of pavement material and a feeder located upstream with respect to a traveling working direction of said road finisher, said feeder comprising a movable substructure, a bulk material hopper located on said substructure for receiving said first grade of pavement material and a first longitudinal conveying device extending from said bulk material hopper up to and over the material hopper of said road finisher for feeding said first grade of pavement material to said first material hopper, the improvement comprising a second material hopper on said road finisher for receiving the second grade of pavement material, a superstructure on said feeder that extends above the bulk material hopper and the first longitudinal conveying device, a second longitudinal conveying and intermediate storage device on said superstructure of said feeder for feeding the second grade of pavement material to the second material hopper of the road finisher, the second longitudinal conveying and intermediate storage device extending up to and over the second material hopper of the road finisher, and a forward section of the second longitudinal conveying and intermediate storage device being adjustable on said feeder relative to the bulk material hopper between a position for receiving the second grade of pavement material and a passive position in which the bulk material hopper of said feeder is accessible for receiving the first grade of pavement material.
In a feeder for feeding pavement material to a first material hopper of at least one road finisher comprising a self-propelled substructure having arranged at a front end thereof a bulk material hopper for receiving a first grade of pavement material and a first longitudinal conveying device extending rearwardly of said bulk material hopper for feeding the first grade of pavement material to said first material hopper, the improvement wherein said feeder has a superstructure extending above said bulk material hopper and said first longitudinal conveying device, a second longitudinal conveying and intermediate storage device on said superstructure for feeding a second grade of pavement material to a second material hopper located on said at least one road finisher or located on a second road finisher located rearwardly of said at least one road finisher, said second longitudinal conveying and intermediate storage device extending up to and over the second material hopper, and a forward section of said second longitudinal conveying and intermediate storage device being adjustably supported on said feeder relative to said bulk material hopper between a position for receiving the second grade of pavement material and a passive position in which said bulk material hopper of said feeder is accessible for receiving the first grade of pavement material.
