BIORESTOR® was developed and is produced in the heart of the Midwest - Sidney, Ohio. BIORESTOR® Asphalt Rejuvenator became available for commercial use in 2004 after diligent research, successful laboratory testing and an extensive in-place history of outstanding performance. Since that time, BIORESTOR® has continued to be a front-runner in the industry with continued testing in laboratory and varied climate in-place settings. We are very proud to be a LEADER in the rejuvenating fog seal industry - See our OUTSTANDING test results in a recent NCAT - National Center for Asphalt Technology evaluation!
