Cold In-Place Recycling
“Cold in-place recycling (CIR) of asphalt pavements has proven to be a viable method of rehabilitating roads that both minimizes user delay and is more environmentally sustainable” – FHWA FOCUS, 2001
Quick, Cost-Effective and Environmentally Friendly
Cold In-Place Recycling (CIR) uses a train of equipment that mills, screens, and crushes the existing asphalt pavement. Typically 3-5 inches is milled off of the pavement. An asphalt rejuvenating material is then blended with the reclaimed material and the recycled mix is laid back down to form a new pavement structure. Additional aggregate or other additives may also be blended in to correct the gradation or improve the mix. The recycled mix may be placed with a paver or it may be bladed. The mat is then compacted. After a 3-5 day curing period, a new surface (typically hot-mix asphalt (HMA) or a seal coat) may be applied. The recycling asphalt may be emulsified, cutback or a soft asphalt cement, and it may have rejuvenator oils, polymers or other additives; or it may be unmodified asphalt. The process moves quickly with minimal traffic delay. The old pavement milled at the beginning of the train is rejuvenated and re-laid at the back of the train.
