Phoenix Industries (PI) today announced it has been awarded U.S. Patent No. 8,404,164 by the U.S. Patent and Trademark Office (USPTO) for its innovative process related to the pelletizing of rubber modified asphalt (bitumen) used in the paving industry.
This addition to PI’s patent and proprietary technology portfolio broadens the company’s intellectual property protection in place for the PelletPAVE™, PelletPATCH™ and PelletRAP™ line of pelletized materials.
The patent covers the pelletization process and formula technology related to creating a pre-manufactured matrix of asphalt and modifiers with an outer shell coating to keep the pellets in a free-flowing form that is transported and stored at ambient temperature, thus saving enormous amounts of energy normally required to keep the asphalt as a molten liquid. At the time of use, the proportional amount of the pellets are mixed, either through a RAP collar of a continuous drum plant or directly into the mixer of a batch plant where it is blended with the heated aggregate to produce a modified hot mix asphalt.
According to PI’s Director of Research and Development, Dr. Serji Amirkhanian, “This patent is a significant development that will let us move ahead with the introduction of new products based on related technology. We have several materials and equipment designs in the pipeline that will expand our product line of green and sustainable innovations for the asphalt paving industry.”
Phoenix Industries is an environmental solutions company that manufactures equipment and provides new technologies for the modified asphalt paving industry.
