What Is Cold In-Place Recycling?
CIR (Cold In-Place Recycling) is one of the most sustainable and resilient asphalt recycling technologies available on the market today.
CIR is an in-place, partial depth, asphalt rehabilitation construction technique that has been successfully performed throughout the United States for over 40 years. This in-place asphalt recycling technique eliminates the need to truck off RAP (Recycled Asphalt Pavement) and import new materials, thereby reducing construction GHG (Greenhouse Gas) Emissions by up to 90% when compared to conventional construction rehabilitation strategies.
The process mills up an existing layer of asphalt at a depth of 3 to 4 inches. The RAP that is produced by the milling process is then screened, crushed, and sized to meet project specifications. The properly sized RAP is then weighed and conveyed to a pug mill where oil is combined with the RAP to make cold mix. This cold mix is put in a windrow and paved in a fashion similar to a hot mix asphalt paving operation.
Performance Equipment Service and its team of skilled tradespeople, coupled with a modern fleet of CIR equipment, allows our team to consistently provide customers with impressive roadway smoothness improvements. Specific attention is paid to the rolling process at the rear of the train to ensure that the compaction of cold mix meets or exceeds project density requirements.
