AbstractA two-continuous-phase sulfur-asphalt composite was developed for use as a road repair material. Two methods to obtain a continuous sulfur phase in a continuous asphalt phase are described. Scanning electron microscopy and mercury porosimetry technique provided evidence for a continuous sulfur phase. Mechanical properties -- determined from hardness, uniaxial tension, and fracture energy measurements -- of the two-continuous-phase sulfur- asphalt composite were studied at 22 and -31 degrees C. Mechanical properties of fiber-reinforced (up to 2% by volume of dacron fibers) sulfur-asphalt composites were also studied.
