Grading a Road Using a Stringline
P/N 7010-0344
5-19
Be sure to check the grade several times in the first 50 feet.
Depending on how accurate the Tracker and the stringline offset from
the edge of the road were "zeroed out", the grade may not be exactly
1.70 feet below the stringline. However, the grade will be consistently
a few hundreths high or low. By checking the grade and knowing how
high or low the grade is being cut, adjustments can be made to get the
desired grade.
Figure 5-23.
After grading the first pass along the edge of the road, make a pass to
move the material away. Just dial the Tracker to 0.00 to match the
previous pass, and the cross slope system will continuing to cut the
slope up toward the centerline.
