Grading a Road Using a
Stringline

In this example, a Sonic Stringline has been set 2.0' above the desired
finished sub-grade. Desired cross slope is 2.0%.

Figure 5-19.

NOTICE

NOTICE

Before grading, always make sure the Cross Slope System
is calibrated and the Tracker reference number has been
"zeroed out". (See Chapter Getting Ready to Grade).
