In the context of aggregates, what does Superpave refer to?

Superpave, which stands for Superior Performing Asphalt Pavements, is specifically designed as a performance-based system for the selection and design of asphalt mixtures. This methodology encompasses various factors such as traffic loading, climate, and particular aggregate properties, ensuring that the asphalt mix is tailored to perform effectively under specific conditions.

It emphasizes the significance of testing the mixtures' performance through various analyses rather than just adhering to traditional material specifications. By focusing on the mixture's ability to resist deformation, cracking, and other distresses, Superpave ensures improved durability and longevity of asphalt pavements. This approach is crucial for professionals involved in asphalt pavement design and construction, as it allows for a more reliable prediction of pavement performance over time.

Other options may outline different aspects of aggregate and asphalt technology, but they do not capture the comprehensive nature of what Superpave entails regarding performance assessment in asphalt mixtures.
