    摘要： Die Erfindung betrifft ein Verfahren zum dynamischen Steuern einer Einbaugeschwindigkeit (v) mindestens eines Straßenfertigers (3) für einen Einbauprozess (E), wobei anhand eines mit dem Straßenfertiger (3) funktional verbundenen Steuerungssystems (2) in Abhängigkeit einer damit festgestellten, veränderlichen Materiallieferleistung (PL) einer den Straßenfertiger (3) mit Einbaumaterial (M) versorgenden Materiallieferkette (L) eine der festgestellten Materiallieferleistung (PL) angepasste Einbaugeschwindigkeit (v) für den Straßenfertiger (3) ermittelt wird, wobei eine Vorverdichtungsleistung (VL) mindestens eines Vorverdichtungselements (6) einer Einbaubohle (7, 7') des Straßenfertigers (3) in Abhängigkeit der ermittelten Einbaugeschwindigkeit (v) zur Konstanthaltung einer mittels des Vorverdichtungselements (6) erzielten Vorverdichtung (V) angepasst wird. Ferner bezieht sich die Erfindung auf ein Straßenbausystem (1) für einen Einbauprozess (E) zur Herstellung einer konstanten Vorverdichtung (V) bei variierender Einbaugeschwindigkeit (v).

    摘要： Construction quality of a road surface is improved. An asphalt finisher (100) includes a tractor (1), a hopper (2) that is provided on a front side of the tractor (1), a conveyor (CV) that transports a paving material in the hopper (2) to a rear side of the tractor (1), a screw (SC) that spreads the paving material, which is transported by the conveyor (CV) and which is sprinkled on a road surface in a vehicle width direction, and a screed device (3) that levels the paving material spread by the screw (SC) on a rear side of the screw (SC) and that is capable of expanding and contracting in the vehicle width direction, in which a rotation speed of the screw (SC) is configured to be changed while the asphalt finisher (100) is moved by the tractor (1) based on information related to a moving direction of the asphalt finisher (100).

    摘要： Provided is a technique capable of suppressing damage to a roadbed during construction of asphalt pavement. An asphalt finisher 100 includes a tractor 1, a hopper 2 installed on a front side of the tractor 1, and that receives a paving material, a conveyor CV that conveys the paving material in the hopper 2 to a rear side of the tractor 1, a screw SC that spreads out the paving material conveyed by the conveyor CV on the rear side of the tractor 1, a screed 3 that spreads and levels the paving material spread out by the screw SC on a rear side of the screw SC, and a controller 50 (front wheel driving force control unit 50B) that controls a driving force of a front wheel 6 of the tractor 1 based on a weight of the paving material in the hopper 2.

    摘要： System for monitoring the wear of a solid plate which, when being in use, has a surface (32) being exposed to abrasive wear, the solid plate being in particular a metal plate of a vehicle, more particularly being a screed base plate (30) and/or a conveyor plate of a paver (10), the system comprising: a through boring (40) in the solid plate, the boring (40) having a boring longitudinal axis (42), a substantially cylindrical part (40a), and an end part (41) adjacent said surface (32), the end part (41) having an end part surface (44) being at least partly conical in cross-section along the boring longitudinal axis (42), and a counter-sunk head screw (c) having a screw longitudinal axis (43), a shaft (50) fitting into the cylindrical part (40a) of the boring (40), and a head (52) with an underside (54) being at least partly conical in cross-section along the screw longitudinal axis (43), wherein a first angle (α) between the underside (54) and the screw longitudinal axis (43) is bigger than a second angle (β) between the surface (44) of the end part (41) and the boring longitudinal axis (42), and that a sensor (60) is positioned at a fixed position on a side of the solid plate being opposite to said surface (32) and being adapted to measure a change (x) of a distance between a tip (51) of the screw (c) and the sensor (60). A method for monitoring the wear of a solid plate, a computer program, a computer readable medium and a control unit are also disclosed.

    摘要： To enhance the quality of pavement of a curved road (RD) . An asphalt finisher (100, 100a, 100b, 100c, 100d, 100e) includes a tractor, a hopper that is provided on a front side of the tractor and that receives a paving material, a conveyor that feeds the paving material received by the hopper to a rear side of the tractor, a screw that spreads the paving material fed by the conveyor on the rear side of the tractor, a screed that levels the paving material spread by the screw on a rear side of the screw, and a controller. The controller is configured to drive the tractor such that a target trajectory (TPS, TPT) is generated based on a line which bisects an area of a road surface leveled by the screed right and left and a predetermined point (Q, P) of the asphalt finisher (100, 100a, 100b, 100c, 100d, 100e) follows the target trajectory (TPS, TPT) . The road surface includes a road surface of a curve portion (LC) of a road (RD) which is a construction target.
