Abstract
An asphaltic coating composition in the form of an emulsion of chemically modified asphalt and a normal, non-modified asphalt in an aqueous emulsification medium. The emulsion can be used as a primer or damp-proof coating and has good adherence to concrete, wooden or asphaltic substrates to yield a coating of excellent physical properties. The chemically modified asphalt and the normal asphalt can be blended prior to emulsification, can be separately emulsified and mixed to form a blended emulsion, or can be individually emulsified in the same emulsification medium.
