Reinforced sulphur-asphalt composites of two continuous phases |
摘要 |
A sulfur-bituminous composite binder material consisting essentially of 60-75% by weight sulfur and 25-40% by weight bituminous material. Optionally a small amount of a fibrous or flake reinforcing material and usually a filler material can be added. The binder is suitable for use as a self-compacting road or pothole repair material. A feature of the composite binder is the presence of two continuous phases which is achieved by mixing solid particulate sulfur with a softened bituminous material at a temperature in the range 120 DEG -150 DEG C. or by mixing liquid sulfur with liquid asphalt with a sufficient shearing mixing action to produce an emulsion of the liquid sulfur in the asphalt which, on cooling produces a continuous, rigid, crystaline and porous sulfur skeleton in the composite.
