Roofing membrane with integrated surface reinforcement

A surface-reinforced bitumen roofing membrane that includes a bitumen compound layer, a fiber mat that is position on or above at least a portion of a top surface of said bitumen compound layer, a bleed blocker layer located between said bitumen compound layer and said fiber mat, and a release liner;

• said bleed block layer includes a polymer material;
• said release liner is a) releasably positioned on a bottom surface of said surface-reinforced bitumen roofing membrane, and/or b) releasably positioned on a top surface of said surface-reinforced bitumen roofing membrane;
• said bitumen compound layer comprises by weight percent:
• Primary hydrocarbon compound
• 25-80 wt. %
• Filler
• 0.5-60 wt. %
• Polymer Modifier
• 0.05-25 wt. %
• Hydrocarbon Resin Process Oil
• 0.05-20 wt. %;
• and wherein said weight percentages of said bitumen compound layer excludes any internal reinforcement layer in said bitumen compound layer.
