There are two kinds of sealing processes: the first method is to spray hot asphalt (or emulsified asphalt) on the surface of the bottom layer; the second method is to spread the emulsified asphalt on the surface of the bottom layer. The first method is relatively simple and economical, so it is widely used.

seize or shear the asphalt emulsion. • DO NOT apply severe heat to pump packing glands or pump casing. The pump may be damaged and the asphalt may become even harder. • DO NOT dilute rapid-setting grades of emulsified asphalt with water. Medium and slow setting grades may be diluted, but always add water slowly to the asphalt emulsion.

Emulsified asphalt is well known and broadly utilized as a preferred roofing material in industrial and commercial applications. Emulsified asphalt came into general use in the 1920's, mostly for spray applications and use as dust palliatives. Emulsified asphalt provides a highly durable and reliable roofing material for a very reasonable cost.

Cement emulsified asphalt mixtures are a kind of potential pavement material, but the adhesion between coarse aggregate and asphalt still needs to be studied.
