Asphalt may seem like an easy material to cut, but the reality is quite different. Its composition, the presence of aggregates, and its high abrasiveness make it one of the most demanding surfaces for diamond tools.

An unsuitable blade or an incorrect cutting technique can cause premature wear, reduce cutting speed, and increase project costs.

At Marathon Diamond, we offer tools specifically designed for these types of applications, providing the perfect balance between performance, durability, and safety.

Why is asphalt a challenge for diamond tools?

Although it is a softer material than concrete, asphalt is highly abrasive due to the mixture of bitumen and aggregates that make it up.

During cutting, this abrasion continuously wears down the diamond segment, so the tool must be designed to maintain its cutting capacity throughout the entire operation.

For this reason, asphalt blades have specific characteristics that set them apart from those intended for other materials.

Use blades specifically designed for asphalt

One of the most common mistakes is using blades designed for concrete or other materials.

Asphalt cutting discs feature segments with a softer binder, which allows for controlled wear of the metal matrix. This process constantly exposes new diamonds, maintaining the tool’s cutting edge even in highly abrasive materials.

Thanks to this design, the following is achieved:

• Faster cutting speed.
• Uniform wear of the segments.
• Better performance throughout the blade’s service life.
• Lower risk of vitrification or loss of cutting capacity.

Maintain constant cooling

Water plays a crucial role during asphalt cutting.

Proper cooling allows for:

• Dissipate the heat generated by friction.
• Reduce premature disc wear.
• Remove cutting debris.
• Improve the quality of the finish.

Whenever the application allows, maintaining a continuous flow of water helps extend the tool’s service life and optimize its performance.

Avoid forcing the feed

It’s common to think that applying more pressure will speed up the work. However, the exact opposite is true.

When you force the blade:

• The operating temperature increases.
• Segment wear increases.
• The machine becomes overloaded.
• Cutting accuracy decreases.

The tool should operate at its own pace, allowing the diamonds to perform the cut efficiently.

Make deep cuts gradually

For jobs requiring a great depth of cut, it is best to make several passes rather than trying to reach the full depth in a single pass.

This technique offers numerous advantages:

• It reduces the strain on the blade.
• It reduces heat generation.
• It improves stability during cutting.
• It extends the tool’s service life.

In addition, it produces a more uniform and precise finish.

The right tool reduces time and costs

In road maintenance, civil engineering, or urban paving projects, choosing the right cutting disc can make a significant difference in productivity.

A blade designed for asphalt allows you to:

• Increase work speed.
• Reduce the number of replacements.
• Minimize downtime for maintenance.
• Lower cost per linear meter of cut.

Investing in the right tool translates into higher performance and lower operating costs.

Experience makes the difference

At Marathon Diamond, we offer diamond blades specifically designed to meet the demands of asphalt cutting, providing solutions that combine wear resistance, fast cutting speed, and a long service life.

Our goal is to help professionals work more efficiently, even under the most demanding conditions.

Because successfully cutting asphalt does not depend on applying more force, but rather on using the proper technique and the tool designed for this type of material.
