How to cut? 

Now that you know why and when it is necessary to cut asphalt, the next stage is digging. There are various ways of doing so, with some standard tools that you can use during the process.

However, these are lengthy processes, and here’s how to go about performing them.

Method 1: Using the circular saw

  • Sweep the area clean

The first and foremost thing you should do is to clean the area where you want to cut asphalt. Use a broom to get rid of any loose elements of the asphalt or debris from there.
It is important because those little chunks could fly up and injure you. The reason behind is the saw collides’ blade with them.

  • Mark the targeted area

It is advisable to label the area for cutting with chalk. Use it to make lines on the Asphalt. According to the amount of space you want to cut.
A chalk line is a coverable line of string that you can elongate just over the ground level. Later, you can pull it up and see a chalk line printed on the ground.

  • Insert a diamond blade in the saw

As you put the diamond blade inside the circular saw, it will cut the asphalt quite effectively. These blades are strong enough to correctly do the job. Unlike, the regular ones that break during the process.
Also, while inserting the diamond blade, ensure turning the saw off. Next, loosen the nut of the blades by using a wrench and turn the saw on.
Then, hold the power trigger facing downwards till the blades start spinning at the optimum speed.

  • Start cutting the marked area

In this step, you have to start working. Dig the diamond blade into the ground and begin cutting slowly.
Keep pressing it gradually till it sinks in the asphalt, ultimately before you drag the blade further.
Knowing when you can proceed further is when you feel the blade facing lesser resistance in the Asphalt. As you get done with the complete line, pull the saw back up. Now release the power button to turn it off.

  • Get rid of the asphalt chunks

Lastly, pull the chunks out of the cut. The ones you’ve made by inserting the pointed part of the shovel into the cut line.
Next, lift them and discard them. In case those parts are too big, use a sledgehammer to tear them into smaller pieces first.

Method 2: Using the chipping hammer (hammer chisel)

  • Run the basics

Like the previous method, clean the debris off first.  Afterward, mark the area with chalk lines to know where to start.

  • Fix both components together

In this step, you have to put fit the chipping hammer and the chisel blade together. For non-linear cuts or short lines, use a narrow chisel blade.
On the contrary, for longer lines, use a wide chisel blade. Next, push the bid’s flat-ended area inside the bottom part of the chipping hammer and lock it in.

  • Turn the machine on

Keep the hammer’s tip on one end of the chalk line with both hands and turn the hammer on. Eventually, it’s up and down motion will start going deep in the asphalt to cut it effectively.
Move it along the chalk line till it covers the removable asphalt completely. Subsequently, the decreased resistance will tell you when to stop.

  • Wipe the asphalt chunks off

In the end, you have to clean the affected asphalt area. Then pick the leftovers up to dispose of them immediately. For bigger chunks, use the hammer to break them down first before discarding them.
