There is an increased need for, and use of, reclaimed asphalt in the production of fresh asphalt. In order to produce a mixture with the required properties, the grade and quantity of binder added to the mixture has to be adjusted to compensate for the age-hardened binder within the reclaimed asphalt. The adjustments increase as the proportion of reclaimed asphalt is increased. In order to reduce the adjustment needed and in order to increase the consistency of the final product, regenerators can be added to rejuvenate the binder. One such product is Itelene ACF 1000, for which some test data is available. That information has been reviewed and further tests have been undertaken to assess the effectiveness of the product. It has been found that the regenerator does recover properties that have degenerated in aged bitumen for their incorporation into a new asphalt mixture.
