Balanced Mix Design

Balanced Mix Design (BMD) is an innovative approach to asphalt mix design that evaluates performance by using specific tests on appropriately conditioned specimens to address potential pavement distress, such as cracking and rutting. This method considers critical factors like traffic, climate, and pavement location to ensure long-term reliability.

By moving beyond traditional volumetric methods, BMD allows for greater flexibility in optimizing mixes including the addition of cost-effective materials like recycled aggregates and additives.

BMD is crucial to improved pavement quality and sustainability as it promotes performance-based decisions, enabling material innovations while balancing cost and durability.

Benefits of Balanced Mix Design (BMD)

• Improved pavement durability and performance
• Cost-efficiency by optimizing material mixes such as asphalt binder, aggregate, recycled material, and additives using fact-based test results.
• Reduction of cracking and rutting
