This document seeks to describe current understanding on the potential benefits and the underlying conditions of using rejuvenators to optimise the reuse of reclaimed asphalt in asphalt production. This document is intended for the asphalt industry to help increase their knowledge level regarding the use of rejuvenators and to provide indicative guidance to enable selection of rejuvenators that are fit for purpose and optimal for the intended application.

You can download two versions of the EAPA Position Paper “Recommendations for the use of rejuvenators in hot and warm asphalt production”:

• The Short version that is also publicly available (by clicking here)
• The Long version with much more detailed information – For EAPA Members Only

There is a need for this guidance as the word “rejuvenator” does not yet have an official definition and there is an increasing demand to classify the various products being made available on the market seeking to be used as a “rejuvenator”. This document does not provide recommended specifications because there is currently no European Commission Mandate to set up a harmonised standard. Therefore, it indicates properties which might be relevant depending on the recycling method used, the properties of the reclaimed asphalt, the required performance of the asphalt etc.

This document does not address the use of ‘in-situ’ pavement rejuvenators as e.g. used in Nordic countries or preservatives which are applied to existing materials without extracting them from the paved area.
