Abstract:A chemically-modified sulfur ca1led SULPHLEX (a trademark of Southwest Research Institute) was studied. This binder consists of 70 percent elemental sulfur and 30 percent of a combination of hydrocarbons which chemically react with molten sulfur. This chemical reaction allows the polymeric, molten sulfur to retain, at least to some extent, certain favorable engineering properties after cooling. The goal of this research was to study not only the engineering characteristics but also the chemical stability and characteristics of this material; the chemical characterization of SULPHLEX is presented in a separate report (FHWA/RD-85/033). This report presents the results of an extensive engineering characterization including: (l) mixture design considerations, (2) flexural fatigue, (3) fracture potential, (4) low temperature fracture properties. (5) deformation potential, (6) creep compliance and stiffness response. (7) aging characteristics and (8) resilient and dynamic moduli properties. In addition a pavement performance prediction of SULPHLEX as a paving material under various climates and traffic conditions was made using a systems pavement analysis approach. This approach consisted of an initial screening of literally thousands of pavement design alternatives by the pavements system Model FPS-BISTRO. This was followed by a detailed analysis of the best alternatives by VESYS IIM, a sophisticated structural pavement subsystem which considers the fatigue, deformation and time dependent/temperature dependent compliance of the materials.
