A joint saw is needed for industrial use on streets, roadways, and highways, as it prevents the damage heavy traffic incurs on a pavement joint, causing the slab to either move up or down. The slab movement commonly leads to subgrade pumping, which causes pavement damage. City planners know that without planned joints, the newly paved street will become riddled with random cracking within the first 72 hours of life. The random cracking is not just an aesthetic issue, it can be a detriment to the overall durability of the street pavement. Thus joints are critical and must be cut in order to control;
“ random cracking, accommodate slab movements, ensure joint locations match load transfer device placements, and divide the pavement into practical construction elements.”

The timing of the cuts are very important, as the hardening concrete will form a line of weakness, causing the concrete to crack below the sawcut instead of cracking randomly on the street surface, this is called an induced crack, and is preferable, as you can plan where the cuts will be made to keep the cracking below the street surface and down to a minimum.
