What to Use When Cutting Pavement?
The blade used in cutting asphalt is different from the one you use to cut other structures such as granite, marble or concrete. A diamond blade with a hard bond is the one to be used because the asphalt is softer compared to other surfaces. On the contrary, some soft bonded blades may not be effective of use when cutting asphalt pavement.
The exposed edge of a diamond blade is worn away while cutting asphalt that will later result to unabated cutting when the said wear is exposed to a new layer of grit. When cutting asphalt, the hard blades are better to use because this easily releases the grit. Likewise, wet and dry are varieties of asphalt cutting blades where the dry one has a softer bond compared to the wet blade. Take note that the wet asphalt cutting blade need need to lubricate and cool while cutting the pavement.
Why Cutting Pavement is Necessary?
For repair or replacement of asphalts, cutting the deteriorated pieces is required in order to fill the potholes. There are appropriate tools and required equipment for cutting pavement and in order to complete the repair project.
What are the Steps in Cutting Pavement?
There are three basic steps to follow when undertaking the repair of asphalt. Whether you are repairing a damaged portion or fixing the pothole, it is important to understand the steps necessary to successfully finish the ob. Here are the basic steps to follow:
Step 1: Sweep – Clear the working area by sweeping the debris like pebbles and rocks to ensure that your saw will be safe during cutting.
Step 2: Mark the Cutting Lines – Cutting the damaged area only will not be effective unless you take solid edges by marking lines a bit wider than the damaged portion. It is a good way to cut the pavement if it is still in a good shape. Using square up edges is better than round patch because the repair can last long. Using a chalk line, mark the area and path the pavement to be cut through denting it with an old screwdriver and a hammer.
Step 3: Doing the Cuts – Check how deep the area to ensure the paving thickness. Then, set the blade to the desired depth. It is important to do a straight cut then stop and lift the blade for the next cutting position. While the blade is still running during asphalt cutting, remember never to turn the saw because this will only break the blade. After-which, you are now ready to remove the damaged portion.
Cable tip: One straight cut path is required when cutting the pavement to run a cable. First mark, then cut, lay the cable and eventually fill the crack.

These tips for maintaining asphalt seem like they would help me take better care of my driveway. I need to repair it every year, so knowing how to care for it would help to reduce the number of repairs it needs. I liked your tip to fill in any cracks that appear. Usually, I’ll see a bunch of cracks once winter is over, so I should take advantage of the warm weather during the spring and use that time to fill in any cracks that I see.

Thanks for sharing all of this advice on taking care of your asphalt pavement, and how to cut it. I had no idea that so many steps are involved in cutting a piece of asphalt– I thought you could just get the diamond blades and cut away! However, if you have to carefully mark everything, then I think it might be better if the cracked asphalt in my driveway was cut by a professional. Unfortunately, the cracks are too thick for fillers, and I want to have it replaced anyways to make it look better. In fact, as soon as I get home from work, I’ll start looking around for a contractor in my area!
