Cold in place (CIP) recycling typically refers to milling the existing asphalt mat up to a depth of 125 mm, crushing the recycled asphalt pavement (RAP) to a maximum size of 37.5 mm, mixing a rejuvenating emulsion into the RAP and laying the material back down on the road via a regular paver or grader. Mix design optimizes the addition rate and the composition of the rejuvenating emulsion. Virgin aggregate can also be added to the CIP recycling train, if required.
