Problems solved by technology

The disadvantage of this "suspension system" is that the use of the "suspension system" makes the structure of the road finisher more complex, since in particular the sensor hardware components are added to the road finisher
In addition, the separate transport and attachment of these additional modules and their independent modes of operation require additional transport, storage and attachment equipment as well as trained operators, which complicates the use of road finishing machines on construction sites and increases manufacturing cost
Another problem with this "suspension system" is that if the subgrade to be built on is uneven or if the angle of attack of the paving screed changes, there may be a discrepancy between the actual layer thickness and the detected layer thickness

Embodiment Construction

[0048] figure 1 A road finishing machine 1 is shown, which produces a pavement layer 2 on a roadbed 3 , on which the road finishing machine 1 is moved in a paving direction R during a paving operation. The road finishing machine 1 is equipped with a height-adjustable paving screed 4 for (pre)compacting the paving layer 2 . The paving screed 4 is attached to a screed bar 5 which is connected at a front towing point 6 to a leveling cylinder 7 of the road finisher 1 . The screed strips 5 are used as levers to translate changes in the position of the leveling cylinders into changes in the angle of attack of the paving screed 4 , in particular to compensate for irregularities 8 in the roadbed 3 .

[0049] figure 2 The road finishing machine 1 is shown in a paving operation. exist figure 2 Among them, the paving screed 4 is configured as a telescopic screed. The first measuring device 9 is located on the screed bar 5 . The measuring device 9 comprises a first sensor unit 10 ...

Abstract

The invention relates to a road finisher (1) for producing a paving layer (2) on a subgrade (3), wherein the road finisher (1) is moved on the subgrade (3) in a paving direction (R) during a paving operation. According to the invention, the road finisher (1) is adapted to use distance measurements (A1, A2, A3, A4) to the subgrade, which distance measurements can be provided to a leveling system (14) of the road finisher (1), similarly as measurements for determining the thickness of the layer (31). The invention also relates to a corresponding method for determining the layer thickness.

Description

technical field [0001] The invention relates to a road finishing machine for determining the layer thickness of a paving layer according to claim 1 and to a method for determining the layer thickness by a road finishing machine according to independent claim 15 . Background technique [0002] In practice, road finishing machines are used in the construction of traffic corridors and road surfaces. Road finishing machines are able to receive material, for example from trucks, and spread it according to road construction requirements. [0003] Typically, so-called leveling systems are used on road finishing machines to control the evenness of the paving layer. These systems typically control the height of the paving screed mounted on the road finishing machine based on scanned references. The references used are, for example, the subgrade over which the road finisher moves, gutter slabs, curbs or reference lines stretched along the paving section. A level sensor is used to ...
