Economic Aspects of High Speed Gravel Roads
The report examines the comparative costs of gravel-surfaced and paved roads capable of carrying traffic safely at 55 m.p.h. Gravel surfaces are found to be a practical alternative to asphalt concrete pavement for rural highways in many areas in Alaska. Construction costs are significantly less as a result of the elimination of paving costs and differences in the requirements for embankment material quality and thickness. Maintenance costs are found to favor paved roads where the embankment and original ground conditions are very good, but favor gravel surfaces where these conditions are fair to poor, and especially where permafrost thaw settlement is a maintenance problem. Dust control treatment of gravel-surfaced roads is found to be necessary for providing safe, high speed travel. The report recommends that gravel-surfaced roads be given greater consideration in transportation planning for Alaska.
