On some jobs, booster tanks are used to refill the distributors close to where asphalt application occurs. These vehicles should be inspected for cleanliness; to guard against contamination; and have the identifying data recorded. Their piping and shut-off valves should be checked for leaks to guard against puddles of asphalt being left behind after they have refilled an asphalt distributor. This is especially important if the distributors are to be filled while parked on the pavement that is to be seal coated.

Sometimes a transporter is used as a booster tank on the job, transporting asphalt from the heater unit to where the distributors are filled directly from the transporter. If asphalt cement (AC) is being shot on the project, it must be shot near 300°F. This would necessitate having an insulated transporter, in order to keep the asphalt hot between the heater unit and the distributor.
