Abstract
A roofing membrane material is disclosed. The material is characterized in that it includes a woven or non-woven fibrous mat having an adhesive asphalt coating, such as a two-layer asphaltic coating applied to one surface thereof. The asphaltic coating can be a first relatively non-adhesive asphaltic material that infiltrates a portion of the fibrous mat and a second, relatively adhesive asphaltic material deposited upon an exposed surface of its non-adhesive counterpart.
