Cold In-Place Recycling – Pavement Interactive

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.
