Abstract

Results of the first stage of a continuing research into design and characterization of dune type sand-sulfur-bitumen mixes are presented. The work is designed to complement and supplement efforts by other researchers in this field so as to produce recommendations for design of pavements. Rheological properties of binders with a wide range of sulfur to bitumen ratios have been measured for 60–70 penetration and 85–100 penetration bitumen. The mixes were made up of poorly graded fine sand with binder contents of 5.5 to 8.0% by weight. Compactibility of these mixes was studied using the Gyratory Testing Machine, and the cured specimens were tested for Marshall stability and flow values.
