Embodiment Construction

[0016] figure 1 Depicted is a schematic diagram of a machine 10 , such as a self-propelled compactor having a pair of rotatably mounted and spaced apart rollers 11 for compacting work material 101 on a worksite 100 . Machine 10 includes a frame 12 and a prime mover, such as an engine 13 . In one embodiment, machine 10 may be configured with a type of mechanical drive system such that engine 13 drives torque converter 14 , which in turn drives a transmission (not shown). A transmission may be operatively connected to roller 11 . The systems and methods of the present invention may be used with machine propulsion and power transmission mechanisms (including hydraulic, electric or mechanical drives) applied in the art.

[0017] A ground engaging work implement, such as blade 15, may be provided. Machine 10 may include a cab 16 that can be physically occupied by an operator and provides input to control the machine. Cab 16 may include one or more input devices 17 through which...

Abstract

A system for determining the compaction state of work material includes a compactor and a compaction sensor system. The controller is configured to determine an empirical compaction state of the work material based on signals from the compaction sensor system and machine characteristics associated with the compaction sensor system.

Description

technical field [0001] The present invention relates generally to machines for compacting material and, more particularly, to a system and method for determining the empirical compaction state of work material at a worksite. Background technique [0002] Compactor machines, or compactors, are commonly used in the construction of buildings, highways, parking lots, and other structures to compact work materials (eg, soil, gravel, asphalt, landfill waste) to a desired density. Additionally, compactors are often used to compact recently moving and / or relatively soft materials on mining sites and landfills. The process typically requires multiple passes over the work material to achieve the desired density. [0003] Usually estimated in various ways to determine whether the desired level of compaction has been achieved. In some cases, compaction can be roughly estimated by determining the ability of the work material to support the machine. For example, the penetration depth o...
