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.

Sripath Asphalt Additives and Proven Durability in Roadway and Roofing Applications

In modern asphalt mix design, the use of high-quality asphalt additives has become essential to improve performance, sustainability, and long-term durability. Whether the goal is to incorporate higher amounts of Reclaimed Asphalt Pavement (RAP), reduce production and compaction temperatures, or optimize polymer-modified bitumen (PMB) blends, additives can help producers achieve these objectives without compromising pavement life. Sripath has developed a suite of innovative additives including ReLIXER®, PGXpand®, [...]

Breaking the 30% RAP Barrier and Achieving High-RAP Content in Asphalt Roadways

The push to increase reclaimed asphalt pavement (RAP) usage has moved from purely a sustainability talking point to a strategic priority for agencies and producers worldwide. Rising material costs, tightening environmental regulations, and growing pressure to reduce embodied carbon have made higher RAP contents increasingly attractive. And yet, despite these incentives, many departments of transportation and asphalt producers continue to cap RAP usage between 20-30%. [...]

Asphalt Rejuvenators vs. Bitumen Softeners: Choosing the Right Additive

Asphalt performance is no longer defined solely by virgin materials. With increasing use of recycled asphalt pavement (RAP), tighter specifications, and sustainability targets shaping modern mix design, selecting the right asphalt additive has become a critical decision point. Among the most commonly discussed options are asphalt rejuvenators and bitumen softeners, two additive categories that are often confused but serve very different purposes. Choosing [...]

How Water Affects Asphalt Sustainability and Durability: From Pavement Performance to Energy Use

Water is one of the most persistent and underestimated forces acting on asphalt roadways. While traffic, climate, and materials all influence pavement performance, moisture often determines how long a surface lasts and how sustainable it truly is. Factors such as how water interacts with asphalt binder and aggregate and the hidden energy costs of removing moisture from aggregate or reclaimed asphalt pavement (RAP) piles are just the start of how water [...]
