ABSTRACT:
A modification of a cold milling machine used to remove concrete and asphalt from an existing highway is disclosed, including a milling drum segmented into two or more sections with the drive train for the milling drums passing through the core of the milling drum and supported via a journal or bearing to the outside of the machine. The width of the milling drum can be varied by replacing one section of drum with a segmented drum that is either wider or narrower. The sections of the milling drum can be added by bolting segments of the drum onto a driven sleeve which telescopes over the drive shaft of the machine. The segments of the milling drum can be readily removed by loosening a few bolts and removing the segments without having to slide a milling drum segment off of either end of a drive shaft.
