Challenges of handling asphalt
Processing reclaimed asphalt comes with several challenges. Feed material can vary significantly, from milled asphalt to large chunks and slabs, making consistent handling and crushing more difficult. At the same time, excessive process steps such as pre-crushing, rehandling or additional preparation increase labour, time and operating costs. Another key issue is product quality: instead of generating too many fines and dust, operators want to preserve as much valuable aggregate as possible. This means the ideal solution must not only handle difficult material reliably, but also operate efficiently, economically and with low maintenance.
Compared with conventional jaw crushers, the ACR Asphalt Crusher combines robust feed handling with the process advantages of roll crushing. It is designed to process difficult asphalt feed such as slabs, chunks and milled asphalt, accepts large feed pieces up to 1,200 mm edge length and 400 mm thickness, and can reduce the material to below 80 mm in a single machine. At the same time, its gentle crushing principle helps minimise fines, preserve valuable aggregate and simplify the overall recycling process through direct feed capability. This means that, for asphalt recycling applications, the ACR delivers the coarse feed capability expected from a primary crusher while also providing a more material-friendly and efficient process.

Controlled Asphalt Size Reduction
Why double roll crushing works well for reclaimed asphalt
01
Gentle Crushing
Slow roller rotation helps process asphalt more gently, reduce unnecessary fines and preserve valuable aggregate in the final product.
02
Direct feed capability
The ACR handles broken-up asphalt, milled asphalt and chunks up to 1,200 mm edge length and 400 mm thickness.
03
Fewer process steps
Asphalt can be reduced to below 80 mm in a single machine, helping reduce pre-crushing, rehandling and operating effort.
One machine. Less waste. More value.

Jaw Crushers vs ACR Asphalt Crusher
| Criterion | Typical Jaw Crusher | ACR Asphalt Crusher |
|---|---|---|
| Primary size reduction |
Strong Very effective for breaking large, hard feed material in a primary crushing step. |
Strong Handles large asphalt slabs and chunks up to 1,200 mm edge length and 400 mm thickness. |
| Asphalt-specific process fit |
General purpose Can process asphalt, but is usually not optimized specifically for RAP value recovery. |
Purpose-built Designed for reclaimed asphalt, slabs, chunks and milled asphalt. |
| Fines control |
Depends on setup Suitable for coarse pre-crushing, but less focused on minimizing unnecessary fines. |
Key advantage Controlled roll crushing helps reduce fines and preserve more reusable coarse aggregate. |
| Single-machine result |
Often one process step May require additional crushing or screening depending on target product size. |
Efficient path Can reduce asphalt to below 80 mm in one machine, with smaller final sizes possible. |
| Material value preservation |
Limited focus Main strength is robust breakage, not necessarily preserving valuable aggregate structure. |
High relevance Gentle crushing supports a coarse, reusable asphalt product with less waste. |
Impact Crushers vs ACR Asphalt Crusher
| Criterion | Typical Impact Crusher | ACR Asphalt Crusher |
|---|---|---|
| RAP processing |
Established Widely used for asphalt recycling and capable of high reduction rates. |
Specialized Built specifically for controlled asphalt size reduction with roll crushing. |
| Crushing principle |
High impact Uses aggressive impact force, which can be effective but may create more breakage. |
Controlled Slow-rotating rollers reduce asphalt in a more material-friendly way. |
| Fines generation |
Material-dependent Can generate more fines depending on feed material, rotor speed and setup. |
Low fines focus Designed to limit unnecessary fines and keep more value in the coarse fraction. |
| Aggregate preservation |
Less gentle Strong impact action can break aggregate more aggressively. |
Material-friendly Helps preserve the coarse aggregate structure in recycled asphalt. |
| Process objective |
High reduction Strong choice when maximum breakage and high reduction are the priority. |
Value recovery Strong choice when the goal is defined output, low oversize and valuable RAP quality. |

Asphat Crusher FAQ
What is an asphalt crusher used for?
An asphalt crusher is used to reduce reclaimed asphalt, asphalt slabs, chunks or milled asphalt into a defined, reusable grain size. In asphalt recycling, the goal is not only to break the material down, but to preserve as much valuable aggregate as possible and avoid unnecessary fines or dust.
Can reclaimed asphalt be crushed directly?
Yes, depending on the crusher design. The ACR Asphalt Crusher is designed to process large reclaimed asphalt pieces directly, including feed material up to 1,200 mm edge length and 400 mm thickness. This can reduce the need for pre-crushing, rehandling and additional process steps.
Why is a double roll crusher suitable for asphalt recycling?
A double roll crusher works with a more controlled crushing principle than many aggressive impact-based systems. This helps reduce excessive fines, preserve the valuable aggregate structure and produce a more usable recycled asphalt material. For reclaimed asphalt, controlled size reduction is often more important than maximum fragmentation.
What final grain size can the ACR Asphalt Crusher achieve?
The ACR Asphalt Crusher can reduce reclaimed asphalt to a final size of less than 80 mm in a single machine. This makes the material easier to handle, transport, screen or reuse in further recycling processes.
What is the difference between an impact crusher and a roll crusher for asphalt?
Impact crushers are powerful and flexible, but they can create more fines depending on the material and settings. A roll crusher crushes asphalt more gently and in a controlled way, which can be beneficial when the goal is to recover usable recycled material rather than destroy the aggregate structure.
Is the ACR Asphalt Crusher suitable for continuous operation?
Yes. The ACR Asphalt Crusher is designed for continuous processing and high throughput applications. Depending on the material and setup, it can process up to 600 t/h, making it suitable for industrial asphalt recycling operations.
How does asphalt crushing reduce recycling costs?
Efficient asphalt crushing can reduce disposal costs, transport effort, rehandling and the need for multiple machines. By turning reclaimed asphalt into reusable material, operators can recover value from what would otherwise be treated as waste.
What types of reclaimed asphalt can be processed?
The machine can process different forms of reclaimed asphalt, including milled asphalt, asphalt slabs, chunks and mixed feed material. This makes it suitable for recycling yards, road construction companies and operators handling variable asphalt waste streams.
