When Should You Schedule Full Depth Reclamation?

When should you schedule full depth reclamation for your parking lot? 

Asphalt surfaces, while durable, require regular maintenance to uphold their structural integrity and appearance. Among the myriad of maintenance and repair methods available, full depth reclamation (FDR) stands out as a comprehensive solution for addressing various pavement issues.

In this guide, we’ll delve into the intricacies of reclamation and discuss when it’s the ideal choice for your parking lot.

Understanding Full Depth Reclamation (FDR)

Full depth reclamation, often abbreviated as FDR, is a pavement rehabilitation method that involves pulverizing the existing asphalt layer along with a portion of the underlying base material. This process creates a homogenous blend of the reclaimed materials, which are then treated with a stabilizing agent to enhance their structural capacity.

Signs That Full Depth Reclamation is Needed

  1. Extensive Pavement Distress: When your parking lot exhibits widespread cracks, potholes, and rutting, traditional maintenance methods like patching or surface treatments may no longer suffice. Reclamation addresses these issues by fundamentally restructuring the pavement.
  2. Deteriorating Base Subbase: If the base or subbase layers of your asphalt pavement are compromised due to water infiltration, poor compaction, or aging, reclamation becomes imperative. By incorporating these layers into the reclaimed mix, FDR restores the pavement’s stability and load-bearing capacity.
  3. Frequent Asphalt Repair: Constant patching and spot repairs are indicative of underlying structural issues within the pavement. Rather than resorting to temporary fixes, opting for full depth reclamation provides a long-lasting solution that addresses the root cause of the deterioration.
  4. Aging Asphalt Pavement: As asphalt surfaces age, they become susceptible to degradation from traffic loads, weathering, and chemical exposure. Reclamation rejuvenates aging pavement by recycling the existing material and reinforcing it with stabilizing agents.

Benefits of Full Depth Reclamation

  1. Cost-Effectiveness: Compared to traditional removal and replacement methods, full depth reclamation offers significant cost savings by utilizing existing materials and minimizing disposal expenses.
  2. Reduced Environmental Impact: By recycling the existing asphalt and base materials, reclamation reduces the need for new aggregates and minimizes waste generation, making it an environmentally sustainable choice.
  3. Improved Structural Integrity: FDR enhances the structural capacity of the pavement by incorporating stabilizing agents that bind the reclaimed materials, resulting in a stronger and more durable surface.
  4. Enhanced Longevity: With proper maintenance, a parking lot treated with  reclamation can enjoy an extended service life, reducing the frequency of repairs and minimizing disruptions to business operations.

The Full Depth Reclamation Process

  1. Pulverization: The existing asphalt layer, along with a predetermined depth of the underlying base material, is pulverized using specialized equipment, such as reclaimers or pulverizes.
  2. Addition of Stabilizing Agents: Stabilizing agents, such as Portland cement, asphalt emulsions, or chemical additives, are introduced to the reclaimed material to enhance its structural integrity and mitigate moisture susceptibility.
  3. Compaction: The treated material is compacted using rollers to achieve the desired density and smoothness, ensuring a stable and uniform pavement surface.
  4. Surface Treatment: Depending on the project specifications, the rehabilitated pavement may receive additional surface treatments, such as chip seal or hot mix asphalt, to further enhance its performance and appearance.

Factors to Consider

  1. Traffic Volume and Load: The anticipated traffic volume and load-bearing requirements of the parking lot play a crucial role in determining the suitability of full depth reclamation. Higher traffic areas may benefit from additional surface treatments to withstand heavy loads and vehicular traffic.
  2. Budget and Timeline: While reclamation offers long-term cost savings, it’s essential to consider the initial investment and project timeline when planning for pavement rehabilitation. Proper scheduling and budget allocation can ensure a seamless implementation process.
  3. Site Conditions: Site-specific factors, such as soil composition, drainage patterns, and environmental regulations, should be evaluated to determine the most appropriate rehabilitation method and materials for the project.
