GSI® Applications
|
 |
 |
|
| Both sonic and slope sensors mounted to the GSI's frame take readings simultaneously to determine pavement smoothness. |
GOMACO's GSI is designed for anyone who needs to measure the smoothness of a surface. |
The GSI monitor was positioned on this paver for easy viewing of the smoothness trace from ground level or from the work bridge. |
 |
|
|
 |
 |
|
| On this project the GSI is mounted to a GOMACO Spanit® Work Bridge. The Work Bridge is attached to the back of a GOMACO GHP-2800 slipform paver. The GSI measures the smoothness results on this highway paving project. |
Smoothness readings are being taken on the Atlanta, Georgia airport. |
|
|
|
|
|
|
Four GOMACO GSI units are mounted to the back of the paver. This provides immediate monitoring to assure proper paver setup and performance or examine for corrective measures that need to be taken.
|
| The GSI took part in the Federal Highway Administration's "Profiler Round-Up" study. Sixty-eight road profilers were compared and verified on two different test tracks, one in Blacksburg, Virginia (above left), and the other in Newville, Pennsylvania (above right). |

|
| The GSI Grade Analysis Tool builds a profile of the grade and estimates the concrete yield of the project. |
This GSI traces four wheel tracks, providing accurate data for the smoothness readings on this two-lane street. |
Here, the GSI is mounted to the back of a GP-2600 and in the center of the paver. The monitor can be mounted anywhere on the paver for easy viewing. |

The rideability of this concrete roadway in Austin, Texas, is constantly being monitored by the GSI.

| The GSI's on-board printer instantly verifies the smoothness of the concrete. |
The GSI measures pavement smoothness behind the texture/cure machine on a project near Onawa, Iowa. |

|
| A GHP-2800 paves the curve on the Martinsville Speedway in Virginia for NASCAR racing. A GSI follows the paver to check smoothness results.

The GSI was successfully tested for repeatability by steering from stringline. The GSI was taken off line and returned to line for retracing. Similar traces revealed excellent repeatability by the GSI. |
|
|
|
|
|
| The GSI can commence tracing right off the morning header, ahead of the texture/cure machine. If used later, saw-cuts, rains or wetness of slab do not affect readings. |
The GSI can operate off the same stringline as the paver. Here it is measuring smoothness directly behind the finishers. |
