Smoothtrac SAS Placement and Setup
Topcon's Smoothtrac® Sonic Averaging System (SAS) is a non-
contacting averaging system that uses multiple sonic trackers to
smooth out the bumps and dips in a mat surface (Figure 6-16). The
non-contacting design allows full maneuverability of the paver
when turning around, backing up or passing over obstacles without
lifting or removing the beam. The screed man can adjust mat
thickness on the control box while standing on the screed. The
Smoothtrac is mounted to the tow arm of the paver, and connects to
System Five with the same coil cord used for the Sonic Tracker.

When mounting the SAS to the paver, follow these simple steps:
1. If the ski is in pieces, connect them together (Figure 6-17).
