Full Depth Recycling (FDR-C) is a pavement rehabilitation technique in which the full thickness of the asphalt pavement and a portion of the underlying layers, along with a small percentage of added cement, are pulverized to provide a homogeneous pavement material. The stabilized material is then compacted in-place with rollers, resulting in a ...

Oct 02, 2011· Waste & Recycled Material In Concrete Technology: Recycled-aggregate concrete containing fly ash is an example of construction material in harmony with this concept, whereby sustainable construction development is useful with satisfactory performance, in both safety and service of structures, at lower costs and with advantages over ordinary concrete.
Typically used in a recycling yard where all material is trucked to the site. Most recycling projects require the operator to produce a sized or specified end product with gradations that need to be met. The example below may help. Job requirements - 30" minus concrete on a demo site to be reduced to 1-1/2" minus base material.
Concrete recycling is increasing in response to improved environmental awareness, legislation, and economic considerations. Conversely, the use of concrete mitigates the use of alternative building materials such as wood, which is a natural form of carbon sequestering. Concrete structures also last much longer than wood structures.
Coco has been involved in numerous P3 projects demonstrating the ability to complete these complex projects on time and on budget. The strength in Coco's P3 capability is the vast vertical integration in all aspects of project delivery from aggregate production, site grading, underground utilities, structure construction, surface grading and surface paving.
