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
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.

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
The subject report contains the most comprehensive published description to date of equipment, materials, quality control procedures, and construction procedures used during the construction of pavement sections with sulphur-extended-asphalt (SEA) binders. It also highlights design procedures and emissions control monitoring used for the project. The reports graphic account will provide useful information to the following class of highway professionals who plan to use SA binders in construction: administrators, materials engineers, construction supervisors, quality control specialists, pavement designers, maintenance engineers, and environmental control specialists.
