Enabling More Circular Road Infrastructure
As the demand for durable and sustainable infrastructure continues to grow, the road construction industry is increasingly looking for ways to reduce its reliance on virgin resources while maintaining high pavement performance.
One promising approach is to increase the use of recycled materials in asphalt mixtures, including:
- Recycled plastics
- Reclaimed Asphalt Pavement (RAP)
- Crumb rubber from end-of-life tires
However, incorporating these secondary raw materials into bitumen can create technical challenges. Differences in material properties may affect compatibility, phase stability and the long-term performance of the pavement.
The SKFP Approach: Combining Circularity and Performance
This is where SK Functional Polymer LOTADER® reactive polymers can contribute.
When used in Polymer-Modified Bitumen (PMB), LOTADER® reactive polymers interact with components of the binder to improve compatibility and help create a more stable polymer-modified system.
This technology can support the incorporation of recycled materials while maintaining the performance required for demanding road applications.
Depending on the formulation, Lotader® technology can contribute to:
- Improved rutting resistance at elevated temperatures
- Enhanced flexibility to help withstand temperature variations and repeated loading
- Improved durability for longer-lasting pavement performance
Building More Circular Roads
The goal is clear: enable greater use of secondary materials without compromising road performance.
By supporting the incorporation of recycled plastics, reclaimed asphalt and crumb rubber, LOTADER® reactive polymer technology can help asphalt producers and road stakeholders move toward more circular and resource-efficient infrastructure.
At SK Functional Polymer, we continue to develop polymer solutions that help turn recycled materials into reliable performance supporting the roads of tomorrow.
