Full Depth Reclamation (FDR)
FDR is the ultimate way to save time, money, and reuse old pavement that's showing signs of damage. The old asphalt and other materials are pulverized, mixed with cement and water, and compacted to produce a strong, durable base for either an asphalt or concrete surface.
The Benefits of FDR
FDR recycles the materials from deteriorated asphalt pavement, and with the addition of cement, creates a new stabilized base. There's no need to haul in aggregate or haul out existing material for disposal. Construction truck traffic is reduced, and there is little or no waste. The recycled base will be stronger, more uniform, and more moisture resistant than the original base, which results in a longer, lower-maintenance life. Most importantly, asphalt recycling costs are usually 25%-50% less than removal and replacement of the old pavement.
Full Depth Reclamation Success in DFW
The City of Dallas has utilized the FDR process since 2004 to promote being a more environmentally friendly city. They've had significant success in reducing road repair materials going to landfills and estimates 80% of all street material is recycled. This incredible example shows just how sustainability can be highly economical with regards to recycled asphalt. Fort Worth has had similar success and completed hundreds of miles of roads using FDR with cement to save an average of $130,000 per lane-mile. All State Paving can utilize these same city street FDR strategies for your project; resulting in saved time and money to create superior pavement with a long lifespan.
Machines Used For FDR
The Road Pavement Mill and Road Recycler are the primary machines needed for milling the surface of existing asphalt and placing new material. The mill is equipped with tungsten carbide teeth that remove the top surface of concrete and asphalt. This loose material is then picked up by the Recycler, blended with a binder, and placed back onto the soil. Water is regularly added to provide the proper moisture content and Compactors press the new soil mixture to create a solid base. The base is then ready for a surface layer of concrete or asphalt.
