Balanced Mixture Design Industry Business Case
A critical step in achieving long-lasting asphalt pavement performance begins with mixture design. An asphalt mixture should possess adequate stability (i.e., resistance to permanent deformation/rutting) and durability (i.e., resistance to cracking) for the intended design application (pavement). Recently, State Departments of Transportation (DOTs) researched and implemented a variety of approaches, including Balanced Mixture Design (BMD), aimed at improving the long-term performance of asphalt mixtures. Defined as “using performance tests on appropriately conditioned specimens that address multiple modes of distress taking into consideration mixture aging, traffic, climate and location within the pavement structure” Balanced Mixture Design means designing the right mixture for the right job.
