HIGHLY MODIFIED ASPHALT BINDERS
Highly Modified Asphalt (HiMA™), a technology developed by Kraton, is designed to enhance durability and processability in asphalt pavement applications. The technology has more than twice the polymer loading of ordinary asphalt, which makes the asphalt act like asphalt-modified rubber instead of rubber-modified asphalt, enabling it to be more resistant to fatigue and deformation. The HiMA mixes are readily workable and easy to lay in the field, enhancing construction efficiency and performance.
HiMA significantly improves the structural pavement’s resistance to rutting and cracking under most circumstances, leading to longer product life. Thinner pavements can achieve equivalent engineering properties, and the asphalt layer’s upfront reduction and paving costs typically offset additional HiMA polymer loading. Both scenarios deliver reduced life cycle costing. This technology also enhances surface durability, increasing resistance to cracking and rutting since thin lift asphalt overlays and inlays, and micro surfacing treatments are regularly used to protect existing pavement from weather and traffic load stresses.
