Full-Depth Reclamation

Full-Depth Reclamation (FDR), is a process that rebuilds worn-out asphalt pavements by recycling the existing roadway.

Old asphalt and base materials are pulverized using a specialized machine called a reclaimer. On top of the pulverized material, water is added to reach the optimal moisture content for compaction, and then a variety of materials such as dry cement, lime, fly ash or asphalt emulsion is incorporated for stabilization. A reclaimer is used again to mix all the materials. After shaping and grading, the new base is compacted to produce a strong, durable base for either an asphalt or concrete surface.

Since this method recycles the materials, there is no need to haul in aggregate or haul out old material for disposal. The vehicle movements are reduced, and detours are unnecessary since it can be done under traffic, making this process more convenient for local residents.

FDR with cement saves money while preserving natural resources by using existing materials and conserving virgin aggregates. Road performance is improved through better stabilization, building a stronger, low-maintenance road that will last for many years.

    The Kelchner crew kept the project moving ahead, even on snow days, when other contractors were forced to stop work by the weather.

    No contractor is 100& perfect, but Kelchner is the most professional, safest and easiest to work with of anyone I have ever seen.
