Abstract
A concrete mixer vehicle includes a mixer drum, an additive admixture system, and a controller. The additive admixture system includes an air inlet valve, a fluid valve, an air valve, and a pump. The controller is configured to operate the additive admixture system to transition the additive admixture system between an additive addition mode, a drain mode, and a system clear mode. The controller transitions the additive admixture system into the additive addition mode and operates the pump until a desired amount of an additive is added to the mixer drum, transitions the additive admixture system into the drain mode for a predetermined amount of time in response to the desired amount of additive being added to the mixer drum, and transitions the additive admixture system into the system clear mode for a predetermined amount of time to clear stagnant fluid or built up mixture from the additive admixture system.
