Abstract: A bucket assembly for a construction vehicle, having a body with a bottom wall, a rear wall, a first side wall, and a second side wall defining a cavity therein, the first side wall having a discharge outlet. A metering system includes an auger moveably attached to the body along a pivot axis within the cavity. The auger has a motor end and a discharge end. A motor engages with the motor end of the auger and is configured for variable movement of the auger about the pivot axis in a first direction for metered dispensing of a construction material through the discharge outlet, and a second direction for controlled mixing of the construction material within the cavity.
