Abstract: According to a method for constructing a cover layer S on a planum M by using a paving screed B the elevation of the paving screed B above the planum M is measured using a reference RZ on the planum M by at least one elevation sensors H and/or the lateral inclination of the paving screed B with respect to the planum M is measured by at least one lateral inclination sensor N. Upon occurrence of a deviation from the target elevation pulling points P of pulling bars 6 of the paving screed B are displaced vertically at a road paver F by levelling cylinders Z. Each levelling cylinder Z is exclusively adjusted over an absolute stroke starting from a selected zero point NP. The absolute stroke is calculated from a measuring result of a reference measurement and by consideration of a construction ratio factor.

Abstract: A road finisher with an internal combustion engine and an engine exhaust pipe has a muffler with an enlarged diameter with respect to that of the engine exhaust pipe, and a pipe for discharging emissions of a building material. The emissions pipe passes though the muffler mounted to the muffler without discharging into the muffler and the exhaust pipe output is supplied to the muffler interior and the muffler has a discharge pipe for the engine exhaust gases.

Abstract: In a road finisher having a spraying assembly for a bitumen emulsion, the spraying assembly has a plurality of spraying modules and one of the spraying modules has at least one pivotable spraying ramp at each side in the area of the carriage of the road finisher.

Abstract: A road finisher with an internal combustion engine, an engine exhaust pipe provided with a muffler having an enlarged diameter with respect to the engine exhaust pipe, and a pipe for discharging emissions of the building material is described. For a constructively simple embodiment easy to be mounted it is suggested to pass the emission pipe without mixing through the muffler and to design the muffler as mounting for the emission pipe.

Abstract: A road finisher F for producing a continuous sprayed carpet T of a bonding agent on a planum has a spraying system S on a vehicle having at least two spraying facilities 11, 11?, 14, 14? which are located offset to each other in the and laterally to the traveling motion direction R and a control device which operates the spraying facilities using a method such that during a traveling motion of the vehicle a sprayed carpet T is produced with front and rear boundaries V, H which are continuous over the width of the sprayed carpet and which are parallel to a respective reference line L which is placed on the planum in front of the spraying facility which is the frontmost in traveling motion direction. The sprayed carpet T is produced such that each spraying facility 11, 11?, 14, 14? first is activated or deactivated depending on the traveling motion with a predetermined distance from the or when reaching the respective reference line L.

Abstract: In a road finisher having a spraying assembly for a bitumen emulsion, the spraying assembly has a plurality of spraying modules and one of the spraying modules has at least one pivotable spraying ramp at each side in the area of the carriage of the road finisher.

Abstract: A paving convoy for producing a bituminous cover layer including a self-propelled road paver and a paving material feeding assembly which is self-propelled and travels in front of the road paver. A paving material conveying device extends from the feeding assembly to the road paver. A spraying module including its own undercarriage and components for storing and deploying bitumen emulsion is provided between the feeding assembly and the road paver. The spraying module has a spraying bar facing the front end of the road paver. The spraying module is either coupled to the feeder assembly by a detachable towing connection or to the road paver by detachable pulling connection.

Abstract: A road finisher has a terminal box from which an electric supply circuit originates to supply electric current to at least one electric heating element for heating work components. A device for supervising the function of the at least one electric heating element includes an induction coil at the terminal box to sense current in the supply circuit and an indicator circuit, preferably of a light emitting diode, is connected to the induction coil for detecting and indicating a voltage induced in the induction coil by the current flowing in the supply circuit of a heating element. In a preferred embodiment, a cable gland is attached to the control box through which a current supply wire of the electric supply circuit passes, and an induction coil is located in the cable gland to sense the current in the supply wire.

Abstract: A mobile feeder has a distributor conveyor band which is adjustable in at least a height direction. The distributor conveyor band is connected to a carrier frame and can be removed with the carrier frame from the mobile feeder. The mobile feeder is equipped with a mounting device for the distributor conveyor band. The mounting device at least temporarily is provided at the mobile feeder, can be set on the ground, and engages the carrier frame from below. Matching connection assemblies releasably connect the carrier frame to the mounting device. Drive assemblies at the mounting device adjust the carrier frame relative to the mobile feeder to a ground contact position of the distributor conveyor band.

Abstract: A mobile feeder B has a distributor conveyor band V which at least is adjustable in height direction. The distributor conveyor band V is connected to a carrier frame T and can be removed with its carrier frame T from the mobile feeder B. The mobile feeder is equipped with a mounting device M, M′ for the distributor conveyor band V. The mounting device at least temporarily is provided at the mobile feeder, can be set on the ground 20 and engages from below under the carrier frame T. Matching connection assemblies A1, A2, A3, A1′, A2′, A3′ releasably connect the carrier frame T to the mounting device. Drive assemblies Z, Z1 at the mounting device and/or at the distributor conveyor band V serve to adjust the carrier frame relative to the mobile feeder to a ground contact position of the distributor conveyor band (V).

Abstract: A pavement-vehicle convoy for applying a cover layer of a paving material on a traffic area, such as a roadway. The convoy has at least two independently driven units with at least one of the units being a road-surface finisher and each other unit in the convoy being either a finisher or a charger. One of the units is a command unit that has a remote control used to help maintain a predetermined desired longitudinal distance between the convoy units and which can be used to help maintain a predetermined desired lateral distance from a reference line. The remote control includes a speed correcting device that utilizes signals from a distance sensor on at least one of the units that is used to detect changes from the desired distance so that speed correction signals can be generated and provided to an operation control device on at least one of the units.
