Setting Surface Stringline
Surface stringline provides a low-impact reference and averaging
solution for steering and grade control. Because it rests close to the
surface, trucks and other traffic can drive over the stringline without
causing control problems and reference damage.
As a grade reference, Pavers use the Sonic Tracker II to track the
stringline, producing a consistent and constant cut. When sighting
down the stringline, problem areas can be spotted, and marked or
fixed, before paving begins.
Surface stringline replaces a contacting averaging ski when a
reference is unavailable or impractical. Averaging skis average out
the irregularities of the surface being cut, but can be impractical,
bulky, complex, and fragile. Surface stringline is simple, more
practical, and easier to maintain than an averaging ski. When
stretched over the ground, surface stringline levels the high places
and bridges the low (Figure 3-1), creating a natural average over a
distance as long as 500 feet.
Figure 3-1. Surface String Averaging
Surface stringline is a verifiable reference for any job, replacing
cumbersome averaging skis. In coordination with the Sonic Tracker
II, stringline acts as 5 to 500 foot long, virtual, and more accurate,
averaging ski.
Sometimes, the surface to be milled contains pot holes or surfaces
too broken to use as a joint match reference Setting elevated
stringline would be too time consuming, especially for small,
divided projects. In these applications, surface stringline provides a
simple, easy alternative.
