Crack sealing machine can be used for sealing the crack for the highways, expressways and other road maintenance process. Effective crack sealing can keep water from entering and weakening the base or sub-base. Crack sealing machine helps preserve the pavement adjacent to the cracks; prevents sand, stone, and dirt from making its way into open cracks causing compressive stresses; and extends pavement life by minimizing crack growth.
The primary benefit of sealing cracks is the reduction of cost in future asphalt repairs, as well as increasing the longevity of your existing asphalt pavement. However, not all cracks can be sealed. When pavement starts to become alligatored, sealing the cracks is a useful repair method, which should not use the crack sealing machine.
As the time of the cracks are noticed and larger than 3mm in width they should be sealed. As the time goes by, cracks should be sealed before the rainy weather hits. This method is to keep water from penetrating into your sub grade layer of your asphalt.
