Download or read book Construction of an Experimental Sulfur-extended Asphalt Pavement written by Kenneth S. Dodge and published by . This book was released on 1982 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the design, placement, and collection of initial data from a sulfur-extended-asphalt (SEA) pavement and a conventional pavement used as a control. 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 Rtes 118 and 202 adjoining the Amawalk Reservoir in Westchester County. Mix temperatures, hot-bin gradations, and toxic emissions were monitored at the plant and the site throughout placement. Aggregates were collected from the hot bin during production of the control and SEA mixes for use in a Marshall mix design. Cores were extracted from both SEA and control pavements 1 month after placement for laboratory testing. Pavement surface properties were also examined after 1 month of service. A Marshall mix design based on hot-bin aggregate gradations was prepared for both the control and SEA mixes after the fact, and it was found that both had been placed at a binder content less than optimum.

Book excerpt: 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.

Download or read book Sulphur Extended Asphalt (SEA) written by Bob M. Gallaway and published by . This book was released on 1977 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Sulfur-extended Asphalt Pavement by : Thomas F. VanBramer
Download or read book Sulfur-extended Asphalt Pavement written by Thomas F. VanBramer and published by . This book was released on 1986 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Download or read book First Field Trial with Sulfur-extended-asphalt (SEA) Binders written by A. E. Gross and published by . This book was released on 1980 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: A total of 4,070 tons of sulfur-extended-asphalt (SEA) pavement was placed on Maine roads during the 1979 construction season. The SEA mix tot& includes 3,300 tons placed on the Interstate and 770 tons placed on a primary highway. The mix was produced in an 8,000 pound batch plant. A 30/70 (15/85) weight blend of sulfur and asphalt was used as the binding agent. The sulfur modified asphalt was mixed by the "Direct Method" by adding the two materials, asphalt first, one after the other into the mix plant asphalt weigh bucket. The SEA Mix was designed by the Hveem procedures by State technicians in the Bituminous Concrete Laboratory in Bangor. Quality assurance of the finished product was determined by State of Maine inspectors at the plant and on the street. After construction, tests were conducted on the SEA Mix to determine the physical properties of the recovered asphalt for a before and after comparison of the modified binding agent. Frictional resistance, deflection and rideability measurements were obtained on both the SEA and the control sections. These parameters produced similar results for both sections. The SEA binder concept used on the experimental project reduced the required asphalt cement by nearly 20 percent. Laboratory tests indicated that sulfur negated the oxidation of the asphalt cement during the plant mix cycle.
