Everything under control
|
| This is, perhaps, the most user-friendly instrument we have ever made. A quick look at the LED scale gives the driver the compaction value (CMV) instantly. |
 |
| Heres an example: the desired CMV is 40. The scale at left shows a CMV = 20. A few more passes are necessary. The middle scale shows that the desired CMV has been reached, and the green light below is lit. On the scale at right, too many unnecessary passes have been made. |

Everything important is recorded
|
If you know where youve been and have stored all the CMV values for each point, you can relax.
The instrument can be connected to a printer and a control-strip can be printed out during compaction runs. This makes it easy afterwards to find the areas lacking sufficient compaction, which may need additional passes. Or where reinforcement work needs to be carried out. Weak points requiring spot tests can also be identified. The contractor is able to thoroughly check on the resultant quality layer by layer. This substantially reduces the possibility of settlement variations. The contractor can show and document bearing capacity to his customer. Surfaces having low bearing capacity are directly indicated and can be immediately remedied.

Full Control
|
|
From where he sits, the operator can exercise complete control of the compacting results. He can reduce the number of passes to the minimum number necessary to reach the desired CMV values, and thus save both time and money.
When the LED scale begins to blink on and off, it is an alert that the risk for double jumps is fast approaching. By avoiding such conditions, the service life of the drum itself is extended, and the danger of crushing the surface material is reduced.
