| Abstract: |
This is part 3 of a 3 part video developed to help local agencies recognize typical problems with gravel roads, understand their causes, and correct them in a cost-effective manner. Part 3 (18 min.) examines maintenance equipment and techniques, beginning with the motorgrader and its functions -- smoothing, reshaping, regraveling, and cleaning ditches. Some new equipment is introduced, including scarifying blades and retrievers. |
