ReLIXER® is a specially formulated elixir of bio-based oils that rejuvenates aged bitumen when recycling and reusing high levels of reclaimed asphalt pavement (RAP) and/or reclaimed asphalt shingles (RAS) in mixes. Sripath’s ReLIXER is the leading asphalt rejuvenator or recycling agent on the market – trusted by customers worldwide and backed by peerless technical support from our in-country agent network. An asphalt rejuvenator is an additive that can restore the functional properties of aged asphalt binder, also known as bitumen. While the benefits of high-RAP mixes are many, there are physical limitations to using large amounts of RAP. Adding an asphalt rejuvenator can restore functional performance of aged asphalt and allow for higher RAP usage, up to 100% in some cases.
Testing High-RAP Mixes with Asphalt Rejuvenators
The use of reclaimed asphalt and recycled asphalt materials is becoming increasingly widespread. High-RAP mixtures, or those defined as those containing more than 25% RAP by total mix weight, can offer significant environmental and economic benefits by reducing reliance on virgin aggregates and binder. However, increasing RAP content can introduce performance challenges. The aged binder in RAP is typically stiff and brittle, which can negatively impact cracking resistance and long-term durability.
