Cold planer

• abstract: A cold planer (also known as a pavement planer, pavement recycler, asphalt milling machine or roto-mill) is a construction machine used to remove bituminous pavement or asphalt concrete from roadways, resulting in a somewhat rough, even surface that can be immediately opened to traffic. This is accomplished by bringing a rotating mandrel or "head" into contact with the pavement at an exact depth or slope.
