Road Reclaimers: Benefits, Uses & Sustainable Road Maintenance

Road maintenance doesn't always require removing an entire pavement structure and replacing it with new materials. Road reclaimers provide an efficient way to rehabilitate deteriorated roads by pulverizing existing pavement and, when appropriate, blending it with underlying materials and stabilizing agents.

This approach can help contractors and municipalities reduce material hauling, reuse existing roadway materials, and improve the structural condition of a road before a new surface is placed.

But what exactly does a road reclaimer do, and when is road reclamation the right solution?

What Is a Road Reclaimer?

A road reclaimer is heavy construction equipment designed to pulverize and mix existing pavement and underlying roadway materials to create a processed base for rehabilitation. Depending on the project, the reclaimed material may be blended with water, asphalt emulsions, cement, lime, or other stabilizing agents.

Road reclaimers are commonly used for full-depth reclamation (FDR), pavement rehabilitation, road stabilization, and roadway reconstruction projects.

Unlike a machine that simply removes the surface layer, a reclaimer can process material deeper into the existing pavement structure. FHWA describes FDR as treating the full asphalt pavement section and a predetermined portion of underlying material to produce an upgraded, homogeneous base.

How Does Road Reclamation Work?

A typical road reclamation project involves several stages:

1. Pulverizing the Existing Pavement

The reclaimer's cutting drum breaks down the existing asphalt and pavement materials to a specified depth. This creates a workable material that can be processed rather than simply hauled away.

2. Mixing and Stabilizing

The pulverized material can be blended with underlying base material and, when required by the pavement design, stabilizing agents such as cement, lime, asphalt emulsion, or other additives.

3. Shaping the Reclaimed Material

After mixing, the processed material is shaped to establish the required road profile, grade, crown, and slope.

4. Compacting the New Base

Compaction equipment densifies the reclaimed material to meet project requirements.

5. Applying the New Surface

Once the reclaimed base has been prepared and meets the project's specifications, a new asphalt or other appropriate wearing surface can be installed.

FHWA identifies pulverization, additive introduction, shaping, compaction, and application of a wearing course as key stages of full-depth reclamation.

7 Benefits of Road Reclaimers

1. Reuse Existing Roadway Materials

One of the biggest advantages of road reclamation is the ability to reuse existing pavement materials. Instead of treating deteriorated pavement entirely as waste, contractors can process it in place and incorporate it into the rehabilitated roadway structure.

This can reduce dependence on newly sourced aggregate and other virgin materials, depending on project requirements.

2. Reduce Material Hauling

Traditional roadway reconstruction can involve removing old pavement, hauling it away, transporting new aggregate to the project, and completing several additional processing steps.

In-place reclamation can reduce some of that transportation because existing materials are processed at the jobsite. FHWA identifies reduced hauling and material disposal as important benefits of full-depth reclamation.

3. Improve Roadway Structure

Road reclamation isn't simply about making the surface look better. Full-depth reclamation can address problems within the pavement and base layers.

FHWA notes that FDR can improve pavement structure and is particularly useful for roads with base or subgrade problems and insufficient structural capacity.

4. Increase Construction Efficiency

A road reclaimer can combine pavement pulverization and mixing into an integrated operation. Depending on the equipment configuration and project design, this can streamline the rehabilitation process and reduce the number of separate operations required.

Faster isn't automatically better, however. Production must still be controlled to achieve the specified depth, material gradation, moisture content, additive distribution, and compaction.

5. Reduce Construction Waste

Road reclamation can reduce the amount of existing pavement that needs to be removed and disposed of. Reusing suitable materials in the roadway helps turn existing pavement into a project resource rather than treating all of it as waste.

FHWA specifically identifies reuse of existing road materials and reduced use of virgin resources as sustainability benefits of FDR.

6. Support Sustainable Road Maintenance

Sustainability is an increasingly important consideration in roadway construction. By processing existing materials in place, reclamation can potentially reduce transportation requirements, conserve aggregate, and minimize disposal.

FHWA recognizes in-place recycling, including full-depth reclamation, as a viable roadway rehabilitation technique that can provide environmental and resource-conservation benefits.

7. Restore Deteriorated Pavements

Road reclaimers can be useful when pavement problems extend beyond the surface. FDR has been used to address issues including rutting, cracking, patching, and inadequate structural capacity.

FHWA performance information identifies severe rutting, multiple types of cracking, and ride-quality problems among conditions that can trigger FDR projects.

Road Reclamation vs. Traditional Reconstruction

Road reclamation isn't appropriate for every project. The right rehabilitation strategy depends on pavement condition, material properties, drainage, traffic loading, structural requirements, and engineering design.

The goal isn't to choose reclamation simply because it uses fewer resources. Contractors should evaluate the existing pavement, subgrade, drainage, traffic demands, material properties, and project specifications before selecting a rehabilitation method.

What Is Full-Depth Reclamation?

Full-depth reclamation, or FDR, is a pavement rehabilitation process that pulverizes the existing asphalt pavement and a predetermined portion of underlying materials and blends them into a stabilized base.

FDR is one of the most important applications for road reclaimers. FHWA states that FDR can typically treat approximately 4 to 12 inches of pavement and underlying material, although the appropriate depth depends on project design and conditions.

Modern FDR equipment can also support larger and more demanding roadway projects when appropriate structural design and traffic-control planning are in place.

When Should You Use a Road Reclaimer?

A road reclaimer may be worth considering when a roadway has:

1. Deep rutting or widespread pavement distress

2. Significant cracking

3. Recurring maintenance patches

4. Weak or inadequate base material

5. Insufficient structural capacity

6. Deterioration extending below the surface

7. A need to reuse suitable existing pavement materials

However, road reclamation should be based on an engineering evaluation rather than surface appearance alone. Poor drainage, unsuitable subgrade materials, contamination, or other structural problems can affect whether reclamation is appropriate.

Road Reclaimer vs. Cold Planer

Road reclaimers and cold planers can both process pavement, but they serve different purposes.

A cold planer is primarily designed to remove a controlled depth of pavement from the roadway surface. A road reclaimer, particularly in an FDR application, processes existing pavement and underlying material to create a new or improved base.

Understanding that difference is important when selecting road rehabilitation equipment. The correct machine depends on whether the project requires surface removal, deeper structural rehabilitation, stabilization, or a combination of processes.

How to Choose Road Reclaimer Equipment

If you're evaluating road reclaimer equipment, consider:

Operating depth: Make sure the machine can reach the required reclamation depth.

Cutting and mixing capability: Evaluate the machine's ability to process the materials and achieve the required gradation.

Machine size: Match equipment size and production capability to project scale.

Operating hours and condition: For used equipment, inspect the cutting system, drum, hydraulics, engine, controls, tires or tracks, and maintenance history.

Project requirements: Consider roadway width, material type, stabilizing agents, production targets, and transportation requirements.

Total ownership cost: Purchase price is only one factor. Fuel consumption, maintenance, wear components, transportation, and expected utilization should also be considered.
