Sulfur-Extended Asphalt Pavement: A Three-Year Progress Report
The 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 Rtes 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.
