Road Widening and Shoulders
The Sonic Tracker and Cross Slope System can be used to cut grade
from an existing road surface for lane extensions or shoulders.
If a barrier wall is being used, make sure the base of the barrier is at
least 2-3 inches from the edge. The Sonic Tracker needs to be
positioned so it is just picking up the edge of the road, but be sure it
will not pick up the base of the barrier well. (See Tracker set up in
Chapter: Getting Ready to Grade)
