Cold In-Place Recycling. Cold in-place recycling (CIR) is the processing and treatment with bituminous and/or chemical additives of existing HMA pavements without heating to produce a restored pavement layer (AASHTO, 1998 [1] ). It involves the same process of cold plant mix recycling except that it is done in-place by a train of equipment.

Milling and grinding aren't the same, however. They each work in a different way to remove material from a workpiece. What Is Milling? Milling is a machining process that involves the use of a milling machine to remove material from a workpiece. Milling machines feature cutting blades that rotate while they press against the workpiece.
