A variety of low-cost asphalt road-surfacing techniques and a unique technology transfer method used to gather information are discussed. The premise is that the employees of the u.S. Department of agriculture, forest service, have a large amount of knowledge and experience on low-cost asphalt-surfaced roads; however, little of it is formally documented. The technology transfer was accomplished by creating an electronic forum that is readily available to this large group of employees. The process facilitated an open discussion of the topic and brought together knowledge and experience from this diverse group of engineers, who are located throughout the united states. The data include numerous processes such as asphalt surface treatments, oil mats, road mixes, desert mixes, and sand seals. Design methods as well as test data are presented. The information, while largely originating from experiences and examples west of the rocky mountains, has application to many other locations.
