Can you saw cut asphalt?

Use a circular saw to cut asphalt. When using a circular saw to cut asphalt, you’ll need a diamond-tooth blade with the proper venting system. The vents between each tooth facilitate the removal of asphalt material as well as provide heat reduction during the cutting process.

Can you cut asphalt with a concrete saw?

Cutting a hard material such as concrete requires a different blade than one used to cut a soft, abrasive material such as asphalt. The saw used with the blade also affects blade life. A tool with high rpm will wear a blade faster than a tool with low rpm, Skaff says.

Why does Blacktop last longer than asphalt?

The main reason behind this is the higher percentage of the crushed stone used in the mixture. Besides, blacktop is heated at a higher temperature—300 degrees, 50 degrees higher than asphalt. Therefore, blacktop paved surfaces tend to last longer since they can easily be resealed.

Do asphalt cutting blades work on asphalt pavement?

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 sustained cutting. Asphalt cutting blades come in both wet and dry varieties.
