Paving Applications
The type of controls you decide to use (elevation sensors, or Slope Sensor and elevation sensor) for paving depends
on the result required for the finished product. Some projects require;
smoothness and improved rideability
consistent mat thickness
the new asphalt to match curb and gutter
the new asphalt to match existing grades
The following sections describe a few examples of paving projects using your Topcon P-32+ or P-32 System.
Paving City Streets with Sonics
When paving city streets, the general requirement is to lay a mat that is so many inches above the base at the
centerline and to match curb and gutter (Figure 132). For this application, sonic control is used on both sides.

1. Before paving, make sure the machine is properly setup, cross slope is calibrated, and trackers are set in the
correct position. See Chapter 5 and Chapter 6 for details.
2. Position right tracker over lip of gutter and left Tracker past the centerline on the base material (Figure 133).

If you are using an ST-3 for elevation control make sure the correct setting is selected in the
Control Box Performance Menu. See “Sonic Tracker 3 (P-32+ System only)” on page 39.
