In some applications, a grade reference outside the screed extension may not be in satisfactory condition, such
as the shoulder of a road or the broken and warped edge of pavement. Traditionally, the screedman would
manually adjust mat thickness on that side of the paver. The non-contacting SAS can be set up over the screed
so full automation can be used. The first three trackers reference the existing grade and the back tracker
references the mat just laid (Figure 112).

When paving with the screed extensions out, there may be a large “head of material” which could be picked up
by the Sonic Tracker. I f this happens, determine how far forward the tracker must be placed on the beam to not
pickup the mix and drill a new mounting hold for the tracker hanger (Figure 113 on page 64). The SAS coil cable
easily reaches the tracker.
