[57] Abstract: A method of waterproofing or damp proofing a protected member having a surface with a sulfur-extended plastomer asphalt binder composition uses a sulfur-extended plastomer asphalt binder composition that includes elemental sulfur, a plastomer and an asphalt binder. The method includes the steps of combining the plastomer with the asphalt binder maintained at a plastomer mixing temperature such that an intermediate asphalt binder mixture forms, and combining elemental sulfur with the intermediate asphalt binder maintained at a sulfur mixing temperature such that the sulfur-extended plastomer asphalt binder composition forms. The method also includes the step of applying the sulfur-extended plastomer asphalt binder composition to the surface of the protected member such that the sulfur-extended plastomer asphalt binder composition contacts, adheres to and forms a layer upon the surface of the protected member. The asphalt binder composition is applied at a temperature no greater than 150 °C.
