Placement When Using Surface Stringline
Sometimes the surface to be paved contains pot holes or the
surface is too broken up to use as a joint match reference.
Setting an elevated stringline is too time consuming, especially
for small, divided up projects. In these applications, surface
stringline would be a good alternative (Figure 6-9). See
“Setting Surface Stringline” on page 3-2 for further details.

Sonic Tracker Placement in Relation
to Screed
As a tracker is moved closer to or further away from the screed, the
response of the screed to an elevation correction changes. A rule of
thumb is to place the tracker about 1/3 to 2/3 the length of the tow
arm forward of the screed pivot point (Figure 6-10 on page 6-9).
