Synthesis of Information Related to Highway Problems. Topic 42-09. Low Cost Solutions for Stabilization and Erosion Control

According to U.S. government records as of 2009 there are estimated to be 42.8 million miles of roads on the planet. Of these, 32.1 million miles (52 million km) comprise rural low-volume roads. In the U.S. there are approximately 4 million miles in the road system of which there are 3 million miles of rural low-volume roads, maintained by some 35,000 local agencies. Low volume roads are often considered synonymous with low cost roads, especially in developing countries, and road construction practice commonly omits any form of surface slope protection (grass plantings, hydro-mulching, etc.). As a consequence, there are often major erosion problems leading to environmental damage and pollution of waterways. Additionally frequent shallow slope failures add to the erosion problem, increase road maintenance needs, and often create road delays and traffic safety problems. Many solutions being implemented around the world by low volume road engineers and managers are successful and low-cost, but are not well-documented. This study will gather information through a literature review, including international sources (especially Nepal, Bhutan, and Indonesia); a practitioner survey; and selected interviews. Contacts and information may be sought from the state LTPPs, the National Association of County Engineers, the American Public Works Association, the US Forest Service, and the state DOTs.
