Cold-in-Place Recycling (CIPR) is an eco-friendly pavement rehabilitation process performed without the use of heat. 2 to 5 inches of the current road surface are pulverized down to a specific aggregate size, mixed with a rejuvenating asphalt emulsion, and then reused to pave that same road. This process is especially efficient in saving costs on labor and transportation.

Recycling and reusing the existing pavement layer does away with the need for purchasing and transporting fresh aggregate. Not only does the customer save on the product that is used, but they also save money on transportation costs due to increased gas prices. Cold-in-Place is good on your wallet and the planet.

The process creates very little pollution because it is a cold process. There is no heat applied to the asphalt and this reduces the noxious fumes that many other processes produce. It is safer for the environment and the workers. With the aspect of saving money and the environment, Cold-in-Place Recycling is a must have process for any road structure in disrepair. 

Preparation:
A mix design must be developed based on core analysis. Drainage, pot holes and shoulder issues must be addressed.

Process:
Core samples are taken from the roadway. These samples are then analyzed to determine the proper process and mix design for the project. Once all testing is completed, construction can begin. Midland offers Type I and Type II CIPR:

• Type I - The first step is to reclaim the top 3-4 inches of the existing asphalt pavement using a milling machine. The reclaimed material is then run through a screener/ crusher for proper sizing based on the mix design. The sized aggregate material is then added to a mix paver where it is blended with asphalt emulsion and paved in place.
  
• Type II - In Type II, the reclaimed material is sized and mixed with asphalt emulsion using a milling machine and placed using a paver.
  
  The newly placed material is then compacted with a combination of steel drum and rubber tire pneumatic rollers.
  
  This entire process is done by means of a combination of machinery referred to as a "train". The pieces of equipment used in CIPR are an emulsion tanker, a water tanker, a milling machine, a crusher, and the Midland Mix Paver.
