Asphalt millings are recycled in almost every new asphalt mix that is produced. Not all of the milled asphalt is reused in new asphalt. Most projects limit millings to no more than 30 percent of the volume of the new mix. There are other uses for millings such as on driveways or on less traveled roads.
The asphalt millings are produced by grinding a bituminous concrete-paved surface which results in the generation of fine particles of bitumen and inorganic material that made up the road surface. D. SOURCES AND QUANTITIES OF ASPHALT MILLINGS.
The Sumerians used asphalt in 6000 B.C. for its shipbuilding industry. Today, asphalt is applied to roofing, sealants, caulking, brake linings, paints, enamels, and most widely used in the paving industry (Asphalt - Science and Technology, 1968). Process Description. Batch Plant Production
Small pieces of asphalt produced by mechanically grinding asphalt surfaces are referred to as asphalt millings. Large millings that have a rich, black tint indicating a high asphalt cement content are best for asphalt recycling purposes. Surface millings are recommended over full depth millings when choosing asphalt millings to recycle.
How Does Pavement Milling Work? Pavement milling, also known as cold planing, is a process that removes part of a paved surface, such as a parking lot or road. Milling can remove just the surface of the pavement, or anywhere up to the entire depth, referred to as full depth removal.

Asphalt pavement is generally removed either by milling or full-depth removal. Milling entails removal of the pavement surface using a milling machine, which can remove up to 50 mm (2 in) thickness in a single pass. Full-depth removal involves ripping and breaking the pavement using a rhino horn on a bulldozer and/or pneumatic pavement breakers.
and liquid asphalt, there is great value in “recycle” as the term relates to Hot Mix Asphalt (HMA) materials. The largest quantity of RAP comes from milling operations. Most often, the original surface mix is made of 1/2-inch aggregate, and since most mixes are made of 1/2-inch or larger rock, operators generally crush all RAP to 1/2-inch ...
