The following factors should be considered prior to determining a rejuvenating fog seal application rate:
TRAFFIC: The type and quantity of traffic should be considered when selecting the amount of asphalt emulsion to be used as well as the emulsion type.
EXISTING SURFACE: The texture and condition of the existing road surface will affect the emulsion quantity and spray rate. A dry porous road surface may need a higher quantity of emulsion.
ASPHALT RESIDUAL: The quantity of asphalt residual in the emulsion can affect the quantity of emulsion needed. The lower the residual the higher the quantity of asphalt emulsion needed.
