Sulfur Extended Asphalt Pavement Evaluation for Baker River Highway, Washington

Book Description
The design, construction, and initial evaluation of the sulphur extended asphalt (SEA) pavement on the Baker River Highway near Concrete, Washington, is summarized in this paper. The initial design testing indicated that the resilient modulus of the SEA mixtures varies not only with SEA ratio but also with time after mixing and compaction. This resulted in using a 20/80 sulphur/asphalt binder ratio. A unique construction feature of this project was the manner in which sulphur was added to the hot-mix. Dry, bulk sulphur was introduced directly into the asphalt weigh bucket (batch plant) for melting.

Book Description
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.

Book Description
This report deals with pavement mixture designs and construction operation of field trials on U.S. 69 north of Lufkin, Texas. The binders used in this field trial consisted of pure asphalt cement for the control sections and 30/70 weight percent of a sulphur/asphalt emulsion as the test binder. All elements of the structural (thickness) design were produced in pairs for comparison purposes with the exception of two thinner sections selected to possibly show distress in two or three years. Otherwise, the thickness designs used in the test sections were those specified by the State Department of Highways and Public Transportation in the conventional section of this highway. Preconstruction laboratory evaluations of mixture properties and field laboratory control measurements are included as a part of this report.
State-of-the-art Guideline Manual for Design, Quality Control, and Construction of Sulfur-extended-asphalt (SEA) Pavements

Pages : 72
Book Description
Sulfur-Extended-Asphalt (SEA) binders save asphalt, a potential energy source, by replacing some asphalt in conventional flexible pavement mixes with sulfur. These new binders appear to possess properties comparable to asphalt. The guideline manual provides the highway community in both public and private organizations with the most definitive state-of-the-art guidelines extant for using these binders. Information on design, construction, quality control, equipment, mixing plants, specifications, and safety is included.

Book Description
This summary report overviews two previously issued study reports. One report assesses the availability and pricing of sulfur with respect to sulfur extended asphalt (SEA) paving mixtures. The second study report concerned a laboratory oriented testing program which was principally used to examine the durability and aging characteristics of SEA paving mixtures.
