Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.

The existing pavement is broken up and may be ground on-site through a process called milling. This pavement is commonly referred to as reclaimed asphalt pavement (RAP). RAP can be transported to an asphalt plant, where it will be stockpiled for use in new pavement mixes, [34] or it may be recycled in-place using the techniques described below.

The advancement of mini computers from 1982 meant that it became economically viable to design complex 3D shapes using a computer. [ 4 ] From 1995 to 1998 DUCT was gradually replaced with a new range of products, which covered the full manufacturing cycle from conceptual design through to manufacture.
Chipseal (also chip seal or chip and seal) is a pavement surface treatment that combines one or more layers of asphalt with one or more layers of fine aggregate. In the United States, chipseals are typically used on rural roads carrying lower traffic volumes, and the process is often referred to as asphaltic surface treatment.
Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purposes, or separation of rock, soil or aggregate material for the purposes of structural fill or land reclamation activities.
