Abstract

Claims (46)

1 . A method of paving a road surface, the method comprising:

spatially measuring an existing road surface by a sensor;

creating a digital target milling profile;

creating a digital target height profile of a road surface to be paved;

calculating a layer thickness based on the target milling profile and the target height profile;

at least partially automatically controlling a milling machine for milling an actual milling profile according to a specification of the target milling profile;

spatially measuring the milled actual milling profile wherein spatially measuring the milled actual milling profile comprises

comparing the actual milling profile with the target milling profile,

recording deviations in a height or an extension of the actual milling profile from the target milling profile, and

adjusting planning data for a new road surface, wherein the planning data for the new road surface comprises the target height profile; and

at least partially automatically controlling a road paver for paving the road surface in accordance with a specification of the target height profile.

2 . The method according to claim 1 , further comprising calculating a need for paving material based on the target milling profile and the target height profile.

3 . The method of claim 1 wherein the target height profile and the actual milling profile are three-dimensional data.

4 . The method according to claim 2 , wherein spatially measuring the milled actual milling profile comprises recalculating the need for paving material.

5 . The method according to claim 1 , wherein spatially measuring the milled actual milling profile comprises recalculating the layer thickness.

6 . The method according to claim 1 , wherein spatially measuring the milled actual milling profile is carried out by at least one measuring device arranged on the milling machine and at least partially during milling.

7 . The method according to claim 1 , wherein controlling the road paver comprises automatically steering the road paver depending on the target height profile.

8 . The method according to claim 1 , wherein controlling the road paver comprises automatically controlling one or more sideshifts of a paving screed depending on the target height profile.

9 . The method according to claim 1 , wherein controlling the road paver comprises an automatic controlling of leveling cylinders and/or at least one compaction unit in dependence on the target height profile.

10 . The method according claim 1 , wherein creating a digital target milling profile comprises creating a travel path of the milling machine and/or wherein creating a digital target height profile of a road surface to be paved comprises creating a travel path of the road paver.

11 . The method according to claim 1 , further comprising spatially measuring a paved actual height profile at least partially during paving and by at least one measuring device arranged on the road paver, and comparing the paved actual height profile with the target height profile.

12 . The method according to claim 11 further comprising passing measured data of the existing road surface and/or of the actual milling profile and/or of the actual height profile to a data processing unit separate from the milling machine or the road paver.

13 . An asphalt paving system comprising:

a scanning vehicle;

a milling machine; and

a road paver;

wherein each of the scanning vehicle, the milling machine, and the road paver has at least one module for position determination and a respective data processing unit;

wherein the respective data processing unit of the milling machine or the road paver is configured to drive the milling machine or the road paver in each case depending on its position;

wherein the scanning vehicle has a measuring device for spatially measuring an existing road surface; and

wherein the milling machine has a measuring device for spatially measuring a milled actual milling profile and the road finisher has a measuring device for spatially measuring a paved actual height profile, wherein the asphalt paving system is configured to perform the method of paving a road surface according to claim 1 .

14 . The asphalt paving system according to claim 13 , wherein at least two of the data processing units are wirelessly connected to each other and/or are each wirelessly connected to a further data processing unit which is arranged separately from the scanning vehicle, the milling machine, or the road paver.

15 . The asphalt paving system according to claim 13 wherein the data processing unit of the milling machine or the road paver is configured to calculate a layer thickness based on a target milling profile and a target height profile.

16 . The asphalt paving system according to claim 15 wherein the data processing unit of the milling machine or the road paver is configured to calculate a need for paving material based on the target milling profile and the target height profile.

17 . The asphalt paving system according to claim 15 , wherein the measuring device for spatially measuring the milled actual milling profile is configured to compare the milled actual milling profile with the target milling profile.

18 . The asphalt paving system according to claim 15 , wherein the measuring device for spatially measuring the milled actual milling profile is configured to recalculate the layer thickness.

19 . A method of paving a road surface, the method comprising:

creating a digital target milling profile;

creating a digital target height profile of a road surface to be paved;

calculating a layer thickness based on the target milling profile and the target height profile;

at least partially automatically controlling a milling machine for milling an actual milling profile according to a specification of the target milling profile;

spatially measuring the milled actual milling profile wherein spatially measuring the milled actual milling profile comprises

comparing the actual milling profile with the target milling profile,

recording deviations in a height or an extension of the actual milling profile from the target milling profile, and

adjusting planning data for a new road surface, wherein the planning data for the new road surface comprises the target height profile; and

at least partially automatically controlling a road paver for paving the road surface in accordance with a specification of the target height profile.

20 . The method of claim 19 wherein paving a road surface comprises resurfacing a road surface.
