Growing traffic and harsh climates demand solutions for safer, more sustainable infrastructure. Kraton innovations for bitumen modification enable the development of durable, cost-effective roads by reducing time and expenses related to maintenance, construction delays and traffic problems. As a pioneer in bitumen modification, our products and global supply network allow for the delivery of superior performance, processability and reliable supply. Asphalt mixes with binders modified by our polymers and chemicals are also recyclable, minimizing environmental impact. Kraton polymer modification options are specifically designed for paving applications. Our styrene-butadiene-styrene (SBS) polymers address rutting and cracking issues and are ideal for hot and cold climates, creating longer lasting, more efficient roads.
Our Highly Modified Asphalt (HiMA), an SBS polymer technology, has more than twice the polymer loading of an ordinary asphalt mix, yet provides the workability of standard modified asphalt mixes. This high polymer loading makes the binder more like a bitumen-modified rubber than rubber-modified bitumen, making it significantly more resistant to fatigue and deformation than ordinary modified bitumen.
SYLVAROAD™ RP1000 Performance Additive from Kraton provides the high-end reuse of recycled asphalt, which improves resource efficiency by reducing the need for new aggregates and bitumen. The additive allows an increased percentage of recycled asphalt (RA), the use of adverse hard RA quality and facilitates the processing of RA during manufacturing and application. It is designed to help restore the flexibility of the binder from the recycled asphalt while maintaining good rutting performance. This significantly reduces the environmental impact produced from road construction by making effective use of existing and less non-renewable resources to ensure road construction is more sustainable.
