Partial depth Cold In-Place Recycling is a major innovation to improve roadways and at the same time reduce the use of new materials and transportion costs. The Links below contain detail on the benefits and uses of CIR and Central Plant recycling.

Identification that the proposed recycling emulsion has been successfully used on at least five 5 other CIR asphalt projects in California over the past five 5.
. Cold in Place Recycle Links. CIR is based on the principle that the in-place bituminous pavement is a sourse of materials that may be used to build a new bituminous layer. The reclaimed asphalt pavement is sized per design specifications and mixed with a recycling agent andor binder in the machines heavy duty chamber before it is.
1 Emulsion and emulsion supplier. During the cold in-place or in-situ recycling process the reclaimed material does not leave the construction site at all but is processed on the spot and reused immediately. Cold In-place recycling CIR is a process that cold mills and recycles the top 2-5 inches of asphalt using a continuous train operation.
Adding emulsion and aggregate improves the strength and durability of the reclaimed material. Cold recycling in place One Technology Numerous Methods. 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 375 mm mixing a rejuvenating emulsion into the RAP and laying the material back down on the road via a regular paver or grader.
Cold In-Place Recycling CIR is a rehabilitation technique that reuses existing pavement without applying heat. Cold in-place recycling CIR process involves a milling machine with a paver mixer. Approval of the Contractor or Subcontractor performing the CIR is at the discretion of the Engineer.
Minimum 98 recycled material saving 300 truck movements on a typical job. Depending on the structural. 20 - 40 faster construction than traditional rehab reconstruction which reduces delays and inconvenience to the travelling public.
Based on the findings and results from prior tasks Table 1 shows the. It can also break and pulverize all of the HMA and some of the base. Almost 100 reduction in material costs only paying for 1 - 4 new emulsion cement andor corrective aggregate if.
Cold in-place recycling CIR is a paving process where instead of applying all-new Hot Mix Asphalt HMA you treat remove and treat the existing asphalt with bituminous andor chemical additives and then use it to pave the road. Cold In-Place Recycling CIR is an on-grade method of pavement rehabilitation that consists of milling the existing asphalt concrete pavement to a depth between 2 to 4 inches. Sometimes an additional module is included crushing this material and screening it to a.
The milling machine breaks and pulverizes a thin amount of the top layer of the old pavement. Generally any road that is a candidate for mill fill is a. Asphalt Recycling Reclaiming Association.
The Cold In-place Recycling CIR to the Engineer. Mixing the cold milled material with emulsified recycling agent and other additives as needed. A CIR train first grinds off the upper layer.
During the CIR process ¾ - 2 inches of existing pavement are pulverized and mixed with an emulsion binder uniquely designed to meet. Cold In-Place Recycling CIR is an environmentally friendly cost-effective method for restoring worn asphalt pavements that exhibit severe cracking and rutting among other distresses without the use of heat. PPRA Road Resource Cold In-Place Recycling.
An extensive literature review on cold in-place recycling CIR mixture designs and requirements along with laboratory testing and pavement performance prediction was conducted in this project. CIR is accomplished without heating the asphalt mixture before or after placement. And overlaying the recycled surface with a new layer of hot.
It normally involves a recycling train consisting of recycling agent tankers a milling machine an asphalt paver. The Process is carried out on site and reuses. The milled asphalt is mixed with additives and the surface is repaved using the recycled milled asphalt mixture.
Through the complete reuse of existing material CIR greatly reduces trucking time and natural resources to significantly lower project costs. 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. This material is crushed and screened to the proper size and recycling agents are mixed in to.
Reduces overall construction costs Mitigates reflective cracking compared to traditional mill and fill Eliminates. Cold-in-Place Recycling involves removing a portion of existing asphalt pavement with a cold planerasphalt mill. CIR is an all-in-one pavement rehabilitation and placement process.
As one of the leading cold in-place recycling contractors serving the industry Rock Solid brings a wealth of expertise to your project. Utilizing cold in-place recycling for asphalt pavement projects is a fast economical and environmentally responsible means of rehabilitating sections of deteriorating roadways. Topped with a chip seal or hot mix asphalt overlay the CIR lift removes deep cracks to form a rut resistant base.
Cold in-place recycling CIR grinds off the top 2 to 6 5 inches of old asphalt pavement crushes and screens it to size mixes it with an asphalt recycling agent and sometimes other additives then paves it on the same roadway. This not only eliminates the need for trucks to make frequent trips to the processing station but also. It involves grinding off the top 2 to 5 inches of the existing asphalt surface and mixing the crushed asphalt with an asphalt recycling agent and placing it back down with a paver.
National Center for Pavement Preservation. Mix design optimizes the addition rate and. CIR can be done in a continuous process and reuses 100 of the existing road materials which makes this system a good option for pavements reaching the end of their life as well as a good alternative for minimal traffic disruption.
Cold in-place recycling CIPR is a continuous multi-step process in which the existing asphalt pavement is cold-milled and blended with asphalt emulsion and aggregate if necessary. Cold-in-Place CIR recycling is a method of removing and reusing the existing asphalt surface. It involves grinding the top 3-6 inches of existing asphalt surface.
Spreading and compacting the recycled mixture. The recycled asphalt mix is then placed onto the existing milled roadway. Cold in-place recycling utilizes the existing pavement through pulverization and heatless repurposing engineered emulsion or foam which produces a rehabilitated bituminous final base layer to be surfaced with microsurface capeseal oil and chip or HMA.
