Cold-in-Place Recycling is an eco-friendly paving 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. 

Process:
Core samples are taken from the road. These samples are then tested to determine the proper materials to be employed during the rehabilitation project. Once all testing is completed, construction can begin. The first step is to pulverize the existing road surface down to a predetermined, properly sized aggregate. The crushed stone is then combined with a stabilizing liquid asphalt content of 1.5% to 2.2% and a water content of 2% to 3%. After the combination is fully mixed, the resulting product is applied where the previous layer was. The surface is compacted just after application.

The entire process is done by means of a combination of machinery called a "train". The pieces of equipment used in the train operation are an emulsion tanker, a water tanker, a milling machine, a crusher, and the Midland Mix Paver.

Uses:

• Total pavement resurfacing and rehabilitation
• Destroys existing crack patterns
• Reverse the affects of severe surface problems such as cracking, rutting, potholes, and more
• Create a "brand new" interlaying layer utilizing the old surface

Benefits:

• Minimizes hauling of excess materials
• Old, dry pavement is reused and rejuvenated
• Bridge clearances and curb heights remain the same
• Process is environmentally friendly
• Preserves resources
• Energy efficient
• Cost effective
