It is cold planing - or milling - of the asphalt surface. This is done for a number of reasons including the following:

-Removing ruts or bumps or irregularities in a roadway before resurfacing.

-Lowering a road surface that is to be resurfaced or treated so that it fits the profile of adjacent roads.

-Removing existing asphalt that is found to be unacceptable.
