The expanded use of reclaimed asphalt pavement (RAP) continues to gain momentum as municipalities seek sustainable, cost-effective paving options. In Northern Ireland, collaboration and interest are growing as asphalt industry leaders look to identify solutions to meet performance standards while advancing environmental goals. A major focus of these discussions is the role of asphalt rejuvenators in enabling effective, high-RAP mix designs. 

 

This topic will be the focus of discussions on November 25, 2025, when Sripath Innovations presents "Maximising RAP Utilisation" to the Institute of Asphalt Technology (IAT) Northern Ireland Branch. The upcoming program will explore how asphalt rejuvenator technology can enable higher levels of RAP integration, helping to reduce reliance on virgin materials and lower production costs while also cutting carbon emissions. 

 

The presentation, led by Herbert Micallef, Technical Consultant at Sripath Innovations, will provide a comprehensive look at RAP use across the United Kingdom and Northern Ireland. The discussion will include economic, environmental, and technical factors influencing RAP adoption at higher percentages. Attendees can also expect insight into current challenges such as cost volatility and material variability. 

 

Central to the conversation will be the importance of selecting an effective asphalt rejuvenator. While aggregates in RAP remain stable over time, the aged binder within oxidizes, becoming stiff and brittle. An ideal asphalt rejuvenator restores the binder's functional characteristics to achieve performance specifications and perform reliably under traffic and weather stress. 

 

ReLIXER® is an asphalt rejuvenator that has demonstrated the ability for high-RAP mixes to meet performance and sustainability goals. Formulated from a proprietary blend of green, bio-based oils sourced from non-food crops, ReLIXER offers a more sustainable way to achieve high-RAP performance and reduce overall carbon footprint. Its high dosage efficiency and compatibility with a wide range of bitumen and RAP sources make it an adaptable solution for producers seeking to maximize recycled content without sacrificing quality. 

 

The IAT Northern Ireland event will bring together industry leaders dedicated to advancing asphalt technology and sustainability across the region. Sripath Innovations looks forward to sharing technical insights and contributing to the ongoing dialogue on building a more sustainable future in road construction.
