RAP Processing Case Study: An Inline System in Action
RAP processing systems are designed to reduce handling, improve consistency, and increase plant efficiency. In practice, these outcomes depend on how the system is implemented and integrated into real operations.
This case study highlights how one asphalt producer restructured RAP processing to eliminate pre-processing steps and improve workflow efficiency.
The Challenge
For many asphalt operations, RAP processing requires multiple steps before the material reaches the plant, often including separate staging, screening, or crushing. For Manatt’s Eastern Iowa Asphalt Division, this approach created unnecessary complexity.
RAP required pre-processing before plant entry, material was handled multiple times before use, and workflow inefficiencies increased time and cost.
The Solution
To simplify RAP processing, the operation implemented a system that processes material inline with plant production, integrates RAP crushing directly into the material flow, eliminates separate pre-processing steps, and aligns RAP preparation with plant intake.

Manatt’s Results
With the system in place, RAP was no longer processed as a separate activity. Material moved directly from intake into conditioning and crushing, was reduced in size before entering the plant, and flowed into production without intermediate staging.
Key outcomes included the elimination of pre-processing steps, reduced material handling, a simplified workflow from jobsite to plant, and more direct integration of RAP into production.
“The Honey Badger allowed us to bring RAP straight off the project and feed it into the plant without pre-processing.” — Todd Powers, Division Manager, Manatt’s Eastern Iowa Asphalt Division
The System in Practice
While results vary by operation, improvements from this type of system change are typically seen in fewer handling steps, lower labor and equipment usage, improved material consistency entering the plant, and more efficient plant operation.

FAQs About the Manatt’s RAP Processing Case Study
What was the main improvement in this RAP processing case study?
The operation eliminated pre-processing steps and reduced material handling by integrating RAP crushing directly into the plant workflow.
How did inline RAP processing change the workflow?
It allowed RAP to move directly from intake into processing and plant feed without intermediate staging.
What role did the RAP crusher play?
The crusher reduced RAP to a consistent size prior to plant entry, enabling direct use without additional processing steps.
Can similar results be achieved in other plants?
Results vary, but operations with multiple handling steps and staged processing often see improvements from a more integrated approach.
