Performance-based design of asphalt mixtures and review

2018-3-5  The principles for design and quality control of asphalt mixtures have not changed significantly over the previous multiple decades and mainly rely on verification of properties of constituent materials, their proportions, and compaction. In more recent years some specifications have been supplemented with performance-based parameters.
