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.
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.
Cold in-place Recycling (CIR) is a rehabilitation treatment consisting of the cold milling of the existing pavement surface (typically 50-125 mm), screening, remixing with asphalt emulsion, Portland cement or other modifiers to improve properties, followed by lay-down and compaction of the reprocessed material in one continuous operation. …

In this research, a polyurethane-modified cold binder (PMCB) was designed and investigated for the fast and high-quality cold in-place recycling of reclaimed asphalt. For the first step, functional group analysis and fluorescent microscopy were used to reveal the curing process and the modification mechanism of the PMCB.
The cold recycling process carried out by a tank truck, WR 240 cold recycler, and HAMM compactor leaves behind a stable surface that can be opened to traffic without a new surface layer, if necessary. The difference lies in the method of paving: When using the WIRTGEN cold recyclers of the CR series, an asphalt paver is usually used.
In cold central plant recycling, the asphalt recycling takes place at a central location using a stationary cold mix plant. Cold in-place recycling (CIR) and cold central plant recycling (CCPR) are proven, cost effective …

Cold in-place Recycling (CIR) is a rehabilitation treatment consisting of the cold milling of the existing pavement surface (typically 50-125 mm), screening, remixing with asphalt …
Cold In-place Recycling (CIR) takes existing asphalt pavement and recycles it in a cost-effective, long-lasting road rehabilitation technique. What is Cold In-place Recycling? Watch on Process In one continuous operation, the top 2 to 5 inches of distressed asphalt are cold-milled to produce reclaimed asphalt pavement (RAP).
Cold in-place recycling, the focus of this webinar, is a process where all or a portion of an existing asphalt pavement is reclaimed, processed on the grade, and used as a …
Learn more. Cold in-place recycling (CIR) is a cost-effective and environmentally friendly method of rehabilitating asphalt pavements. It involves milling the existing pavement, mixing it with a ...
recycling process. Cold In-place Recycling may be either full-depth or partial-depth [1]. Full-depth CIR is commonly known as full-depth reclamation and stabilization. The work is performed with a pulverizer and the end result is a mixture of recycled asphalt pavement, base material and an asphalt binder. This process is performed at a
Cold in-place recycling (CIR) is a pavement rehabilitation process in which a distressed asphalt pavement is milled to a specified depth, the reclaimed asphalt pavement (RAP) is pulverized and mixed …
In-place recycling can reuse all the old pavement back into the highway. The hot-mix asphalt (HMA) plant recycling process can reuse 25 to 35 percent of the old, reclaimed asphalt pavement effectively, by blending it back in with new HMA for a highway project.
Cold Central Plant Recycling Cold Central Plant Recycling (CCPR) - a process where the asphalt recycling takes place off site or at a central location utilizing a stationary plant. Existing RAP stockpiles can be utilized or milled from an existing roadway, stockpiled, processed, hauled back and placed.
the presence of heat during the recycling process. There are two separate processes used; Cold Central Plant Recycling (CCPR) and Cold In-Place Recycling (CIR). We will be discussing only the CIR process here. The CCPR process is discussed in the Cold Mix Asphalt section. The advantages of Cold In-Place Recycling are as follows:
