Interest in the use of sulfur in highway pavement construction has been stimulated by unpredictable increases in cost and the relative uncertainty as to the future availability of asphalt cement (a/c) along with the potential surplus of sulfur in the near future. These events have led to the development of a new binder: a sulfur- extended-asphalt (sea) binder. This new binder replaces some of the asphalt with sulfur in conventional asphalt paving plants. The mix material can be transported, laid, and compacted with standard paving equipment. Studies of sea pavements indicate that their properties are comparable and in some cases may prove to be superior to those of conventional asphalt pavements. The manual presents state-of-the-art guidelines for design, quality control, safety factors, and construction of these newly developed pavements. A nonproprietary, direct mixing method and four proprietary methods of producing the sea mixtures are described.
