摘要：
A stable, thixotropic aqueous bitumen dispersion containing no emulsifier is prepared. Alkaline earth metal hydroxide and an aluminum salt are brought into contact to form an aqueous aluminum hydroxide gel. Molten bitumen is dispersed in the gel. The dispersion has a good shelf life and is stable with respect to electrolytes and chemically active construction materials.
