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.

Book Description
The purpose of the project constructed in Florida was to design, build, and evaluate a bituminous base course using sulphur as an asphalt cement extender. This evaluation was developed in a manner consistent with procedures used in base satellite projects constructed throughout the state. The test sections are located in Alachua County and were incorporated as a part of the new construction of a four-lane divided roadway. The project itself consists of one control section and seven test sections, each approximately 600 feet (183 m) long. Four of the test sections have SEA binders.

Book Description
This report assess the availability and pricing of sulfur with respect to sulfur extended asphalt paving mixtures. The assessment includes a review of past and current trends as well as sulfur estimates up to the year 2000 for the United States and specifically the State of Washington.

Book Description
Sulfur-Extended-Asphalt (SEA) will become increasingly more important in the future as the supply of asphalt dwindles, the cost of asphalt increases and the sulfur supply exceeds demand. SEA binders had been used successfully in conventional stack plants and this study proves that these binders can also be used in dryer-drum plants. Emissions problems (SO2) did exist with the dryer-drum plant used, but with wet scrubber capability this problem can be solved. This study involved the placement of two test sections and the report presents a description of the work. As a result of this study, it is also advised that the dryer-drum plant's binder control system be calibrated before SEA concrete mix is produced, and also the water susceptibility of the mix be studied as part of the design.

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.
