Abstract

The present disclosure considers a system and method that can predict soil compaction and machine-specific productivity rate across multiple soil conditions without requiring site-specific samples and multi-variable lab testing. The method and system disclosed here can utilize predictive algorithms combined with a soils database to predict soil response to compaction energy across a range of soil moistures for the range of compaction machines available to predict compaction performance.

Claims (38)

1. A system for forecasting soil compaction comprising:

an user interface configured to receive compaction data;

a database configured to provide compaction data;

a controller configured to determine a machine performance characteristic based on compaction data; and

a communication device configured to communicate the compaction data between the database or between one or more machines; and

wherein the compaction data includes a desired soil density input, a soil input, a machine characteristic, or a productivity parameter.

2. The system of claim 1 , wherein the soil input does not include information specific to a soil compaction site.

3. The system of claim 1 , wherein the communication device includes at least one of a wireless communication network and a landline.

4. The system of claim 1 , wherein the database further includes data related to lift thickness.

5. The system of claim 1 , wherein the soil characteristic includes a water content of the soil.

6. The system of claim 1 , wherein the machine performance characteristic includes the number of passes for a specific machine to reach the desired soil density input.

7. The system of claim 1 , wherein the machine performance characteristic includes the number of passes for multiple machines to reach the desired soil density input.

8. The system of claim 7 , wherein the controller is configured to recommend a type of machine to be used for soil compaction based upon at least one of the desired soil density input, the soil input, the machine characteristics, the performance parameters, and the machine performance characteristic.

9. The system of claim 8 , wherein the machine characteristics includes at least one of a yoke mass, a drum mass, a drum diameter, a drum width, a drum frequency, or a isomount stiffness.

10. The system of claim 6 , wherein the controller is further configured to determine a travel route for a specific machine.

11. The system of claim 7 , wherein the controller is further configured to determine a travel route for multiple machines.

12. The system of claim 1 , wherein the controller is configured to update the machine performance characteristic based on dynamic measurements a soil characteristic during a compacting event.

13. A method for forecasting soil compaction including the steps of:

providing a desired soil density level;

providing at least one soil characteristic;

providing at least one machine characteristic;

calculating a machine performance characteristic from the desired soil compaction level, at least one soil characteristic, and at least one machine characteristic;

storing the machine performance characteristic in a database;

predicting a compaction level based on at least one soil characteristic, the machine characteristic; the machine performance characteristic, and the desired soil compaction level;

communicating the predicted compaction level to at least one machine; and

compacting soil to the desired soil compaction level with the at least one machine in response to the predicted compaction level.

14. The method of claim 13 , further including recommending one or more machines for soil compaction based on the predicted compaction level.

15. The method of claim 14 , wherein recommending one or more machines includes factoring in machine operational costs.

16. The method of claim 13 , wherein at least one soil characteristic is a water content value.

17. The method of claim 13 , wherein at least one machine characteristic is a lift thickness value.

18. The method of claim 13 , further including wirelessly communicating the predicted compaction level to the one or more machines.

19. The method of claim 13 , wherein predicting the compaction level is based on performing dynamic measurements of the site specific soil characteristic during a compaction event.

20. A machine comprising:

an user interface configured to receive compaction data;

a controller configured to determine a machine performance characteristic based on compaction data;

a communication device configured to communicate the compaction data between a database or with a second machine;

wherein the compaction data includes a desired soil density input, a soil input, a machine characteristic, or a productivity parameter; and

wherein the database is configured to provide compaction data.
