Abstract
An asphaltic sheet comprising an asphaltic component including an asphalt binder and expandable graphite.
Claims11
An asphaltic composite sheet comprising:
- (i) an asphaltic component including a fabric that is saturated with an asphalt binder, said asphaltic component including and first and second planar surfaces;
- (ii) particulate disposed on said first planar surface of the asphaltic component, wherein said particulate consists of expandable graphite;
- (iii) a polymeric layer laminated to said first planar surface of the asphaltic component so that the particulate is disposed between the polymeric layer and the first planar surface of the asphaltic component;
- and
- (iv) a release member removably secured to said second planar surface of said asphaltic component.

An asphaltic composite sheet comprising:
- (i) a first asphaltic layer including an asphaltic binder composition, said first asphaltic layer having first and second generally planar surfaces;
- (ii) a fabric having first and second generally planar surfaces, said first planar surface of said fabric being in contact with the first planar surface of the first asphaltic layer;
- (iii) a second asphaltic layer including an asphaltic binder composition, said second asphaltic layer having first and second generally planar surfaces, said first planar surface of said second asphaltic layer being contact with the second planar surface for the fabric;
- (iv) particulate disposed on the second planar surface of the second asphaltic layer, wherein said particulate consists of expandable graphite;
- (v) a polymeric layer laminated to the second planar surface of the second asphaltic layer so that the particulate is disposed between the polymeric layer and the second planar surface of the second asphaltic layer;
- and
- (vi) a release member removably secured to said second planar surface of said first asphaltic layer.
