Cold planer

From Wikipedia, the free encyclopedia

A cold planer (also known as a pavement planer, pavement recycler, milling machine or rotomill) is an engineering vehicle used to remove bituminous or asphalt concrete from roadways, resulting in a smooth, even surface. This is accomplished by bringing a spinning mandrel or "head" into contact with the pavement at an exact depth or slope. It is normally fed by conveyor into a dump truck, but can be left in place or "wind-rowed" to be removed at a later date.
