Cutting Asphalt: A Different Blade

Cutting asphalt requires a unique blade that is different than one you would use to cut other surfaces such as concrete, marble, or granite. Because asphalt is softer, it requires a diamond blade with a hard bond. Other soft-bonded blades are not effective on asphalt pavement cutting. 

With a diamond asphalt cutting blade, the exposed edge is worn away as it cuts through the asphalt. Wear on the blade exposes a new layer of grit, resulting in unabated cutting. Hard blades release grit easily while cutting asphalt. Asphalt cutting blades come in both wet and dry varieties. A dry blade has a softer bond than a wet asphalt cutting blade. Wet blades require water to cool and lubricate a cut while pavement cutting.

Cutting asphalt is always necessary for asphalt replacement and frequently required for asphalt repairs that involve cutting away deteriorating pieces of asphalt to fill potholes. When cutting asphalt to complete a repair job, you’ll need to have the appropriate pavement cutting tool, as well as the materials and equipment to fill cracks and asphalt equipment for repairing potholes.

Repairing Potholes

To repair or "patch" potholes, begin by marking the area to be patched. This area should extend at least one foot outside the hole. Cut asphalt to create a square-edge hole. This will create sound material to provide restraint against movement of the patch. Do not use a jack hammer in a rocking fashion to remove asphalt which can weaken the bituminous surrounding the pothole. Instead, use an asphalt cutting blade for the best results when cutting asphalt.

The area that will be patched then needs to be cleaned of debris. If the area is wet, it should be blotted dry before patching. Next, begin filling the hole with asphalt material, placing the mix against the edges first. Finally level and spread with an aluminum paving rake. Do not over-rake which can lead to coarse material rising to the surface.

If you are an asphalt repair contractor or you’re responsible for large expanses of asphalt, you may want to consider an asphalt hot box which can hold hot asphalt for patch work for up to 14 hours. This versatile asphalt box can be used all year-round, even in the winter, to heat asphalt for patching. Asphalt Kingdom offers a 4-ton hot asphalt box with a two year warranty for less than $6,000 with delivery direct to your door.
