INITIAL ANALYSIS OF THE SULFUR-EXTENDED TEST TRACK CONSTRUCTED AT WASHINGTON STATE UNIVERSITY

Due to shortages and price increases of asphalt, researchers, oil companies and governmental agencies are exploring the possible utilization of substitute binders and asphalt extenders for pavement construction. These explorations have produced new emerging technologies such as the recycling of asphalt, asphalt rejuvenation, and asphalt extension through the use of wood lignins or sulfur. This report evaluates the sulfur-extended asphalt, and is based upon recently acquired data from the Washington State University (WSU) test track. A brief description of the state-of-the-art of the extension of asphalt with sulfur is presented in Chapter I. A brief description of the Lufkin, Texas and the Boulder City, Nevada field trials is presented in Chapter II to give the reader a better understanding of current field trials. Further details on the construction of the WSU test track are given in Chapter IV.
