FOEN 4220
FOEN 4220. Low-Volume Road Design. (3) Lec. 2 hrs/wk, Lab. 3 hrs/wk. Prerequisites: FOEN 3040, BSEN 3220. Engineering design of low volume, unpaved roads, especially for forestry applications, including preconstruction planning, construction and maintenance, horizontal and vertical alignment, earthwork volume and distribution analysis, cost analysis, and best management practices. Fall.
Required for students in the Forest Engineering curriculum.
Textbook: Instructor-compiled materials reproduced through Custom Publishing, Bookstore, Auburn University.
Course Objectives: Upon completion of the course the student will be able to properly design a road taking into account the following criteria: horizontal alignment; vertical alignment; earthwork; topographic location including grade and road spacing; construction methods and equipment; soils constraints; water quality issues, erosion control, and Best Management Practices; road maintenance; and stream crossing methods and proper sizing techniques.
Topics Covered:
- Forest road definitions and specifications
- Preconstruction planning - general considerations, location, design, road spacing
- Road maintenance/erosion control
- Erosion control
- Road problems - slides/discussion
- Road design - Paper location
- Horizontal curve design and layout
