    A relatively low viscosity diluted asphalt emulsion is used for fog seals. To coat and waterproof pavement surface, fog seal material should fill pavement voids. The emulsion should have a low viscosity and be slow-setting in order to penetrate enough into the surface before it breaks (Fog Seal Guidelines, 2003). SS-1, RS-a,
