Innovative Initiatives in Road Design and Construction

Certain design practices, such as use of rolling dips, outsloped roads, or low-water stream cross- ings, are very cost-effective and practical but typically apply to low-volume, low-speed roads because of safety concerns, vertical alignment issues, or unacceptable traffic delays. The design standards for these roads are those of the Class A and Class B access roads as provided in the Unpaved Forest Road Handbook (8/74). As a general guideline, sufficient access is typically achieved when 1 mile of PFAR is developed for each 500 acres of

Jan 28, 2019 Dirt and Gravel Road BMP Guide Introduction There are close to 400 miles of dirt and gravel roads in the Culpeper District. Dirt and gravel roads are low-volume roads that have relatively low use and provide service to residences and agricultural, logging and recreational areas. Most dirt and gravel roads are privately maintained and serve The road standard selected in the planning stage defines the required travel width of the road surface. The road design process uses the travel width as a departure point from which the necessary subgrade width is derived. The road design process which deals with fitting a road template into the topography uses the subgrade width for cut and ...
