Verifying Grade
Verifying grade requires measuring the distance from the cut
ground to the Sonic Stringline. To check grade, use a Grade
Checking Lath to check the levelness and depth of cut with the
Sonic Stringline.
The following figures show an example of a hub offset of 1.5 feet
from the edge of the road, and a hike-up of 2.0 feet.
1. Construct a Grade Checking Lath using a lath, a level bubble,
nails, and standard hand tools as shown in Figure 3-16.
