ReLIXER Archives

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.

Video: How Do High-RAP Mixes Dosed with Rejuvenators Age?

TRANSCRIPT FROM VIDEO: Balanced mix design that incorporates Reclaimed Asphalt Pavement dosed with a rejuvenator should consider adherence to performance properties both now and many years after wear and weathering. Testing should include an evaluation of how the aging process impacts these mixes to ensure durability and long-term performance. Simulated aging tests for measures of the Cracking [...]

RAP, Recycling / Rejuvenating Agents, and Roadway Sustainability

New drivers for sustainability in asphalt roadway production continue to arise as departments of transportation look to minimize their carbon footprint without sacrificing performance. A recent article published in the February 2025 issue of AsphaltPro highlights the importance of using higher amounts of recycled materials in roadway development through the use of reclaimed asphalt pavement (RAP) and an effective [...]

Understanding Asphalt Rejuvenators – Frequently Asked Questions

The global asphalt market is projected to reach 225.9 million tons by 2030. This is largely attributed to rapid growth in global infrastructure as demand for both new and refurbished roads takes the spotlight. Yet there are concerns that increasing road projects will impede environmental conservation efforts aimed at net zero carbon emissions. One way the industry [...]

Video: High-RAP Mix Case Study: Lab Test of 100% RAP Dosed with ReLIXER

TRANSCRIPT FROM VIDEO: While high-RAP mixes include any mix with more than 25% Reclaimed Asphalt Pavement, some departments of transportation are looking to push the envelope on RAP usage. When using an effective rejuvenator, RAP usage of up to 100% is possible while maintaining performance specifications. A field trial demonstrated the viability of 100% RAP mixes with [...]
