Title: MODULUS PROPERTIES OF PLASTICIZED SULFUR MIXTURES
Accession Number: 00622192
Record Type: Component
Availability: Find a library where document is available Abstract: Plasticized sulfur is a total replacement for asphalt cement. As a result, the potential for using plasticized sulfur in lieu of asphalt cement in paving mixtures is attractive in this day of capricious supply and pricing of petroleum products. The modulus properties of selected plasticized sulfur mixtures were studied. The plasticized sulfur binders consist of about 70% elemental sulfur and 30% of a combination of hydrocarbons that chemically react with molten sulfur. The results of modulus characterization include resilient modulus, creep stiffness, dynamic modulus, flexural modulus, and relaxation modulus. They also include a comparison with asphalt cement modular properties. The study concluded that plasticized sulfur mixtures exhibit similar modulus properties and are stiffer than asphalt concrete. They also exhibit well-defined viscoelastic response at higher temperatures. These conclusions were consistently substantiated by each of the moduli evaluated.
