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 feasibility of utilizing a sulphur-extended-asphalt binder for roadway pavements was examined when approximately 625 tons of SEA pavement were placed on three cargo area roadways at The Port Authority of New York and New Jersey's John F. Kennedy International Airport. The mix design was based on standard Marshall test procedures using a 70/30 asphalt cement/sulphur ratio (by weight) binder in a standard Port Authority graded bituminous pavement. The SEA mix was produced in a conventional asphalt concrete batch plant modified to accept the liquid sulphur and placed using standard asphalt construction methods and equipment. Initial tests indicate success of the trial and a valuable place for sulphur in pavement technology.

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 report documents post-construction performance of a sulfur-extended asphalt (SEA) pavement and a conventional pavement used as a control, monitored over a 3-year period. The SEA pavement used 30-percent sulfur by total weight of the binder. Both pavements were placed under New York State specifications during the summer of 1980 on routes 118 and 202 in Westchester County, New York. After 3 years, overall condition of both the SEA and control pavements was satisfactory. The two did not differ significantly in deflection, rutting, friction, or aggregate degradation. Data obtained from analysis of pavement cores showed that the stability of the SEA mix was equal to or higher than that of the control at all ages. Similarly, its resilient modulus was greater at all ages and temperatures. Although tensile strength ratios measured for both mixes indicated a potential for stripping, virtually none was observed in any of the field cores for either pavement at any age.

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
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.
