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.

Technical Specifications for Asphalt Rejuvenation

By incorporating reclaimed asphalt and recycled asphalt materials into new mixtures, producers can reduce reliance on virgin materials, lower costs, and support circular economy initiatives. However, higher reclaimed asphalt pavement (RAP) content introduces new performance challenges that must be carefully managed to ensure long-term pavement durability. The primary challenge stems from the aged binder contained within reclaimed asphalt pavement. Over time, asphalt [...]

Sustainable Bitumen Additives to Extend Asphalt Lifespan

Sustainability may be one of the defining priorities in pavement and roofing construction. Governments, producers, contractors, and asset owners are all under pressure to reduce emissions, conserve resources, and improve the long-term environmental performance of infrastructure. However, one misconception still persists throughout the industry: that sustainable solutions require sacrificing cost, durability, or long-term performance. Advances in asphalt chemistry are proving the opposite. Sustainable bitumen additives are helping producers create [...]

Cost Savings and Lifecycle Value in the Asphalt Industry

Asphalt production and paving operations are under constant pressure to balance performance, efficiency, and cost. Agencies, producers, and contractors are expected to deliver durable pavements while managing fluctuating raw material prices, energy expenses, maintenance demands, and increasingly complex mix designs. As a result, the use of asphalt additives and asphalt modifiers has become an important strategy for optimizing production costs and long-term pavement value. Advanced additive [...]

Asphalt Additives: Modern Chemistry Transforms Road Construction

The asphalt industry has undergone a significant transformation over the past few decades driven by advances in materials science, tighter performance requirements, and the increasing use of recycled materials. At the center of this evolution is a class of technologies broadly known as asphalt additives. Once considered optional enhancements, additives are now a core part of modern mix design, fundamentally changing how asphalt or [...]
