Shortly after the First World War, the U.S. Army Corps of Engineers did extensive research into developing a liquid blend of maltenous type petroleum solvent. With refined oil tar products proving to be the most complete performer, development of three component sealer rejuvenators began.

Over the past decade, these specially designed, treated and distill-processed Refined Bitumen R12 based rejuvenators have been improved and are now widely adopted as part of accredited highway preventive maintenance programs across the globe.

An overwhelming amount of laboratory and field test data confirms that in-situ chemical rejuvenation represents a cost-effective alternative compared with traditional reconstruction techniques.
