Why More Agencies Are Choosing Cold In-Place Recycling
Across Illinois and the Midwest, transportation agencies are facing a common challenge: how do you maintain and rehabilitate aging roadways while making the most of limited infrastructure budgets?
With thousands of miles of pavement requiring ongoing maintenance, agencies are looking beyond traditional rehabilitation methods and embracing solutions that maximize the value of every dollar invested. One method that continues to gain momentum is Cold In-Place Recycling (CIR).
By rehabilitating existing asphalt rather than removing and replacing it, CIR provides a cost-effective, sustainable, and efficient solution for many roadway projects, helping agencies extend pavement life while minimizing disruptions to the traveling public.
A Smarter Approach to Road Rehabilitation
Cold In-Place Recycling is a pavement rehabilitation process that mills the existing asphalt surface, processes the material on-site, blends it with a recycling agent, and places it back as a renewed pavement layer. A new asphalt surface is then applied to complete the roadway.
Unlike traditional reconstruction, CIR makes use of the pavement that’s already in place. This reduces the need for new aggregate and asphalt while preserving much of the existing roadway structure.
For many roadways experiencing surface deterioration, cracking, or oxidation, but still possessing a sound underlying foundation, CIR offers an excellent balance between pavement preservation and full reconstruction.
Maximizing Infrastructure Budgets
Every agency is tasked with managing more roadway miles than funding often allows.
Cold In-Place Recycling helps stretch available budgets by reducing material costs, limiting trucking requirements, and shortening construction schedules. Those efficiencies allow agencies to rehabilitate more lane miles within the same capital improvement program.
Rather than focusing solely on the initial project cost, many agencies evaluate the long-term value CIR provides through improved pavement performance and extended service life.
Keeping Roads Open and Communities Moving
Road construction inevitably impacts drivers, businesses, and nearby residents. One reason agencies continue to adopt CIR is its ability to reduce construction-related disruptions.
Because much of the existing material remains on-site throughout the process, projects often require fewer truckloads entering and leaving the work zone. This helps streamline operations while reducing traffic impacts and improving overall project efficiency.
For communities, that can mean shorter construction durations and a quicker return to normal traffic patterns.
Supporting Sustainable Infrastructure
Sustainability has become an increasingly important consideration in public infrastructure projects.
Cold In-Place Recycling aligns with those goals by reusing the existing asphalt pavement instead of sending it off-site for disposal. Reusing existing materials reduces the demand for virgin aggregates, decreases transportation requirements, and lowers overall material consumption.
The result is a rehabilitation method that not only benefits project budgets but also supports responsible resource management.
A Proven Solution for the Right Roadways
While CIR is not the answer for every project, it has become a proven rehabilitation strategy for many county highways, municipal streets, and rural roadways.
Roads that exhibit surface distress but maintain adequate structural support are often strong candidates for Cold In-Place Recycling. By restoring pavement before deterioration becomes more severe, agencies can delay costly reconstruction while improving ride quality and extending pavement performance.
Selecting the right rehabilitation strategy depends on pavement condition, traffic volumes, roadway function, and long-term maintenance goals. CIR is one of several tools available to help agencies make the most of their infrastructure investments.
Experience Matters
As more agencies throughout Illinois and the Midwest recognize the benefits of Cold In-Place Recycling, partnering with an experienced contractor becomes increasingly important.

Frequently Asked Questions
What is Cold In-Place Recycling (CIR)?
Cold In-Place Recycling is a pavement rehabilitation process that reuses the existing asphalt pavement by milling, processing, and placing it back on the roadway before applying a new asphalt surface.
Why are more agencies choosing CIR?
Many agencies choose CIR because it helps extend pavement life, reduces material consumption, shortens construction time, and allows more roadway miles to be rehabilitated within available budgets.
Is CIR suitable for every roadway?
No. CIR is best suited for pavements with surface deterioration but a stable underlying structure. A pavement evaluation helps determine if it is the appropriate rehabilitation method.
What are the environmental benefits of CIR?
Because CIR reuses the existing pavement, it reduces the need for new materials, minimizes trucking, and supports more sustainable roadway construction practices.
How does Dunn Company help agencies with CIR projects?
Dunn Company works with municipalities, counties, and transportation agencies to evaluate roadway conditions and determine whether Cold In-Place Recycling is the right rehabilitation solution for each project.
