Cold Central Plant Recycling - PPRA

Cold Central Plant Recycling (CCPR) is the process in which the asphalt recycling takes place at a central location using a stationary cold mix plant. The stationary plant could be a specifically designed plant or a CIR train minus the cold planing machine set up in a stationary configuration.

Cold In-place Recycling (CIR) Treatment Types

Cold in-place recycling (CIR) process involves a milling machine with a paver mixer. The milling machine breaks and pulverizes a thin amount of the top layer of the old pavement. It can also break and pulverize all of the HMA and some of the base. This material is crushed and screened to the proper size and recycling agents are mixed in to ...

Cold Central Plant Recycling - PPRA

RAP Gradation: RAP should be sampled and tested for maximum particle size with either air dried or wet field samples prior to or after the addition of the recycling agent. CCPR Recycling Agent Content: Recycling agent content (emulsified or foamed asphalt) should be checked by evaluating the mass of recycled material against the volume of recycling agent used for a single tanker.

Structural performance and sustainability assessment of ...

20-01-2019  This paper aimed at assessing the structural performance and sustainability of cold recycled asphalt pavements. Four cold recycling technologies were investigated, including the cold central-plant recycling with emulsified and foamed asphalt binders (i.e., CCPR-E and CCPR-F), and the cold in-place recycling with emulsified and foamed asphalt binders (i.e., CIR-E and CIR-F).

What is Cold-in-place recycling and what are its advantages?

07-04-2011  What is Cold-in-place recycling and what are its advantages? Cold-in-Place (CIR) recycling is a method of removing and reusing the existing asphalt surface. 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.
