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.
