Abstract:
This invention provides a novel composite of bitumen and recycled polymers from post consumer and pre consumer manufacturing scraps for use in asphalt to increase its viscosity at higher temperature, desirable in pavements of warmer regions. This additive also improves tackiness for use in asphalt sealant applications and roofing membrane. This invention meets federal government objective of increasing post consumer wastes in asphalt.
