Abstract:
This report discusses the design, placement and preliminary evaluation of a sulfur extended asphalt pavement. Initial data on frictional characteristics, rideability and strength was also obtained. In 1981 an overlay consisting of sulfur extended asphalt (SEA) pavement was placed on the I-95 interstate system in Maine. Approximately 26,200 tons of the experimental pavement was used. Three different blend weights, 30/70, 20/80 and 10/90 of sulfur to asphalt, were incorporated in the project. The SEA pavement was mixed by the "Direct Method", first adding asphalt then sulfur, using and 8,000 pound batch plant. The SEA mix was found to produce low concentrations of Hydrogen Sulfide (H2S) and Sulfur Dioxide (SO2) and high concentrations of total suspended particulates (TSP) around the paver during the laydown operation.
