Deep Cold in–Place Recycling (DCIR) incorporates the processes of both pavement reclamation and cold in place recycling by stabilizing the asphalt pavement and the granular base to depths of up to 500mm.
DCIR provides a deep stabilized base that increases in strength through its development of the performance characteristics of asphalt base pavement through the incorporation of emulsified asphalt as a stabilizing agent.
This process employs the use of an asphalt reclaimer specifically intended for the pulverization of asphalt pavement. The reclaimer is equipped with a milling head containing up to twice the amount of teeth as a pavement profiler, which provides material capable of passing most gradation specifications for 25mm minus base material.
Deep cold in place recycling is recommended for use when there is a need for an increase in the structural strength of a road. This process can eliminate the need to import large quantities of virgin aggregates and or the need to excavate and replace unsuitable subgrade materials.
The re–use of these in place materials in this process also reduces the drain on natural resources while also lessening the strain on the environment and disposal sites.
DCIR proves to be a cost effective alternative to total reconstruction using performance proven solutions which also lighten the load on infrastructure and reduce inconvenience to the public by shortening construction durations and equipment traffic. dump fees and purchases of virgin aggregates, reducing the depletion of resources, and lightening the load on waste sites. The addition of these materials also increases the structural integrity of the roadway by increasing the granular thickness of the aggregate base.
