Every asphalt pavement is made of two components: aggregates and bitumen. The role of aggregates is to provide structural support. Bitumen is a glue holding aggregates together. Because asphalt pavements flex under traffic, bitumen needs to be strong and resilient. Kraton polymers have a unique molecular structure, which when mixed with bitumen, enhances their durability by adding flexibility, elasticity, and toughness over a wide temperature range. These features reduce the bitumen’s sensitivity to extreme temperatures and significantly enhance its performance properties.

LOWER PAVEMENT LIFECYCLE COST
Consider the following figure showing cost reduction per mile of pavement of a 40 year time period. Performance enhancements may lead to a dramatically reduced agency lifecycle cost depending on bitumen modification level.
