Cold 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.


Pothole Patching

Patches are a common method of treating an area of localized distress. Patches can be either full-depth where they extend from the pavement surface to the sub grade or partial where they do not extend through the full depth of existing pavement .
