All existing asphalt pavement is removed through a full-depth milling process, pulverized to a specific gradation, reclaimed and recycled with the existing aggregate base. It may also involve soil corrections and removal of aggregate base. Sweeping Our mission is to clean city streets in order to provide safe conditions for all modes of transportation.
