NCAT: Balanced Mix Design

Balanced Mix Design (BMD) is an advanced approach to asphalt mix design that integrates performance testing to ensure the pavement mixture meets specified criteria for durability and resistance to various forms of distress, such as cracking and rutting. Unlike traditional volumetric-based methods, BMD employs performance tests on appropriately conditioned mixtures, considering factors like traffic, climate, and pavement structure. This methodology allows for greater flexibility in material selection and encourages innovation, often leading to cost savings and enhanced pavement longevity. By focusing on actual performance outcomes rather than solely on mix proportions, BMD aims to produce asphalt mixtures that perform better in the field, ultimately leading to longer-lasting and more sustainable pavements.
