In most industries, the experts use diamond blades with a strong bond to cut the asphalt for ensuring a cleaner cut. They are destined to release the grit easily without getting stuck while cutting the asphalt.
Not just that but there are many different types of equipment, such as asphalt saw for commencing with the cutting work.
After you have arranged the tools, you need to follow the ideal steps to commence with the asphalt saw cutting job.
In this article, you will know about some of the details associated with the asphalt saw cutting, along with an explanation of the use of different types of equipment.
Regular Asphalt Saws
Different types of asphalt saws are available in the market, for making it easy to cut through the asphalt surfaces.
There are basically two types of saws available with the top brands such as Husqvarna & Stihl, namely walk-behind and hand-held asphalt saws. These machines are meant for the industries that handle road repair, electrical work, plumbing work, or others by cutting a section of the road.
Here is a detailed explanation of the two types of saws mostly preferred for the job.
Handheld Asphalt Saw
Handheld Asphalt Saws are smaller in size but are very much effective.
They are meant to be handled with bare hands with the utmost protection. You need to bend down to the ground, while you are gripping the saw with both your hands. One hand would rest on the rear side of the asphalt saw, while the other will be on the top, to push the saw blade down and forward on the length mark.
You can run the blade back and forth to ensure that the cut is deep enough.
After you are done cutting one side of the section, you can use the top hand to release the blade from the ground and lift it to reposition it on another length.
In this way, the handheld asphalt saw is implemented for cutting the road surfaces at ease.
Walk Behind Asphalt Saw
The walk-behind saws are also known as the road saws, which do not let you bend all the way down for handling the machine all by your hands. It eventually makes the asphalt saw cutting work easier as compared to the handheld saw
It has a control panel on a dashboard like structure near the handle area, and a lever attached to give directions to it. This helps the operating person control the path of the cutting.
It has a water nozzle continuously spraying water to the blades to control the excessive heat generated in it.
The person walking behind can push it forward and also pull it back to ensure that the cutting is correctly.
After one section is done, the operating person will lift the blade handle, and reposition the road saw to the next length that needs cutting and repeat the process again.

Basic Asphalt Saw Cutting Steps
Before you go ahead and read about the available equipment for cutting the asphalt, you need to know about the three basic steps that you must always follow, irrespective of the type of cutting equipment you use.
The three basic steps include:
Clean the Asphalt Surface
Before you touch the saw on the asphalt surface, you need to make sure that there is no debris or dirt present on the surface. It is so because, due to the presence of dirt, debris, stones, or pebbles, the cutting job will be obstructed, and it might also damage the blades.
You need to start by removing all the bigger and visible stones, pebbles, and debris from the surface. After that, you can go ahead and clean the area by sweeping it properly.
After you have properly done the cleaning job, you can go ahead asphalt saw cutting jobs.
Note: Cutting the asphalt with debris on the surface will result in inappropriate cuts, and maybe damage the saw blade or operator.
Mark the Lines
After cleaning the surface, the next step that you must take is to mark the cutting paths. You do not want to run the saw blade blindly to give it a random cut.
As per the requirements, mark the cutting path on the asphalt. Mark the lines a little wider to provide yourself with a chance of reviving if the saw cuts slightly in a different tangent. You can use chalk for marking the lines directly on the surface of the asphalt.
After you have done that, you can go ahead to the next step, which is cutting.

Cut one length and then lift your saw to reposition it for cutting another length of the stone as per the marks. If you turn the blades from one length to another while it is still cutting, you would eventually damage or break the blade.
After you have cut all the sides according to the mark, you can remove it.
