How to Cut Asphalt With a Circular Saw
When using a circular saw to cut asphalt, you will need a diamond-tooth blade with the correct ventilation system. The vents between each tooth facilitate the removal of asphalt material as well as provide heat reduction during the cutting process. When cutting material masonry with a circular saw, use a worm screw instead of a conventional one as working with material masonry can put a great amount of stress on a power saw. Asphalt blade the worm will take some stress torque off the electric motor saw, which can help extend the tool’s life. The things you will need
- Pencil
- chalk box
- circular saw
Asphalt Cutting Blade
Personal Protective Equipment
Place two marks on the asphalt to indicate the cut line using a brightly colored pencil for easier visibility. Take a line between the two marks using a chalk from the box.
Insert the properly vented diamond-tooth saw blade into a circular saw designed to cut asphalt materials. From checking the circular saw to make sure the housing, cable, and all safety features are in good working order before using the tool.
Rest the front lip of the cutting table circular saw on the ground and line up the blade with the cut line indication. Pull back on the rear blade holder to expose the blade. Squeeze the saw of the trigger power and allow the blade to spin at full throttle.
Gradually swing the blade down into the asphalt. Moving the saw back and forth while making the first plunge cut in the asphalt this will make the hole slightly larger than the cutting blade which will help prevent pots and blade damage. .
Stop the circular saw, while the blade is still inside the cut, if you hit dirt or stone. Set the cutting table circular saw by releasing the swing nut at the front and pushing it down onto the table, so that the blade does not cut to the thickness of the asphalt.
Raise the blade of the cut slightly and squeeze the saw trigger to allow the blade to spin at full throttle. Swing the back of the blade down into the cut and push the saw slowly forward to allow the diamond-tooth of the blade to cut through the asphalt material.
Releasing the trigger feed circular saw to allow the blade to stop inside the cut once you reach the end of the cut. Lift the saw from the cut and place it to the side. Avoid contracting the hot blade housing or blade to avoid burns.
Tips & Warnings
Always wear personal protective equipment, such as eye protection, earplugs, and a dust mask, when cutting masonry materials with a circular saw.
Cut masonry and asphalt materials in a well-ventilated area, with minimal foot traffic.
Advanced state of degradation: Who says cracks means infiltration of rain and who says water, frost and thaw, says appearance of the famous potholes which are now part of Quebec folklore. They demonstrate the marked progress of the degradation of sections of your parking lot. Fortunately there are also 2 possible solutions to extend the life of the paving.
Fill the pothole with hot asphalt, compact it, apply a bonding binder around the perimeter of the hole, taking care to draw a rectangle or a square (for aesthetic reasons), apply a 2nd layer of asphalt and compact again. (Average lifespan 5 years)
Cut a rectangle or a square around the pothole, remove the existing asphalt, level with 0-20 mm stone, taking care to compact well, Asphalt blade coat the edges of the existing asphalt with bonding binder, apply a layer of at least 50 mm thick hot asphalt and compact. (Average lifespan 8 to 10 years)
Other Advantages of Asphalt Paving:
Asphalt pavements cost around 50% of the price of its uni-stone equivalent for a roughly equivalent lifespan, as it should be noted that uni-stone tends to move more than asphalt because of the greater water infiltration in its joints. Appropriate uni-stone treatments cost on average 4 times as much as those for asphalt. It must therefore be admitted that the cost benefit ratio clearly favors asphalt pavements.
