Milling is the procedure of removing one or several layers of old asphalt off the existing road in order to achieve the correct elevation for the new asphalt to be applied. The "Milling Machine" is supplied by a contractor that has won the bid for that year. The machine and crews supplied are scheduled to come in for usually a week of intense milling. Many township trucks must be supplied to haul the material away from the machine to a stockpile. The speed of the machine and distance traveled constitutes a need for many trucks.
