Professionals know that cutting concrete is different from cutting asphalt. This is because asphalt is softer than any other surfaces such as granite and concrete. It also means that soft bonded blades won’t be as useful in cutting its surface let alone giving you a clean cut. That’s why the best tool for asphalt cutting is a diamond blade with a hard bond. The harder the blade, the more it cuts cleanly.
But before you start with the cutting, here are three things you must know:
Clean the work area.
It is essential to clean the surrounding area before working. Remove any debris or dirt from the floor. Start by removing any large objects such as rocks or large debris that can obstruct you from cutting the asphalt accurately. After getting rid of the large objects, the next thing you need to do is to sweep the area to get rid of all the small pebbles, dirt, and sand since these objects can damage your blade and saw resulting to poor quality cut.
Marking the lines.
Once the surface of your working area is clean, proceed by marking the path for your cuts. Cutting asphalt is done either to repair an existing surface or to replace an old one. To effectively do the job, it is best to mark the surface you’re going to cut with lines. Mark off the lines using chalk directly on the asphalt surface, and then use a screwdriver and hammer to dent the line that you intend to cut.
Cutting the asphalt.
After the area has been cleaned and the mark has been placed, you can now proceed with the cutting job. First, know how deep the surface you’re cutting so you can set your saw to the correct setting. Once that’s done, cut one length of the area of asphalt that is being removed then stop the blade and then lift the saw to re-position for your next cut. Never try to turn the blade while it’s cutting since that can break the blade and result in damage.
To avoid future asphalt damages, immediately fill the cracks once they appear, and makes sure to seal coat every two to three years.
