Enhancements in the control of asphalt mixture quantities are vital to uphold precise production accuracy. This holds particular significance as the majority of funds for asphalt mixture production originate from the Federal Government, making it crucial to maintain accurate proportions to ensure the intended performance of the mixture is observed. Various techniques aimed at refining quantity control were explored by adjusting equipment and conveyance methods. Extensive document analysis was conducted to discern current practices adopted by State Departments of Transportation (DOTs), AASHTO standards, and plant equipment manufacturers. The proposed strategies suggest a shift from the volumetric to the weighing approach where quantity control would be more precise.
