Full-depth reclamation is a road base recycling process in which existing asphalt, chip seal, and stone/sand base material are blended with a chemical modifier to produce a reconstructed roadway. As a result of the process, the recycled base is stronger, more uniform, and more moisture resistant than the original base, resulting in a long-life, low-maintenance pavement.
During the process, a mix design utilizing the existing roadway materials helps determine the proper chemical modifier, application rate and depth of treatment. By utilizing the road’s existing aggregates, Specialties can provide full-depth reclamation solutions quickly, efficiently and usually at a lower cost than a complete reconstruction process since there is no need to haul in aggregate or remove old material for disposal. In addition, the process reduces truck traffic and there is little or no waste.
Furthermore, full-depth reclamation contributes to more sustainable environments in the communities in which Specialties operates, most notably:
- Less jobsite truck traffic lowers carbon emissions and reduces fuel consumption
- By recycling and reusing existing asphalt at the construction site, no asphalt material is hauled away, thus conserving landfill space
In fact, asphalt pavement is America’s most recycled product. According to the National Asphalt Pavement Association, 90 million tons of asphalt pavements are reclaimed annually with more than 80 percent of that total being reused or recycled.
Available nationwide, our full-depth reclamation services offer a shorter construction time than traditional removal and replacement techniques, and in some cases, motorist traffic on the affected roadway can resume to normal levels on the same day.
- We pulverize the existing roadway with a roto-tiller to provide a uniform blend of materials and proper gradation for treatment
- Following pulverization, our crews add a chemical modifier (Portland cement, lime, asphalt emulsion or liquid asphalt) via dry application with Specialties’ specially constructed spreading equipment, or placed in a slurry form via ready-mix or tank equipped spreaders. A proper mix design reveals whether one or more of these modifiers will provide a suitable blend based on the existing materials to be treated.
- Once we complete the blending, our teams then compact and grade the reclaimed roadway for overlay with asphalt or concrete
