What is asphalt sealing?
Sealing asphalt cracks on highways: Crack sealing is considered a preventive maintenance method. There are two general methods for sealing cracks: sealing the crack and filling the crack. Waterlogging and crack filling in asphalt pavements are essential and important maintenance activities that are necessary to reduce the ingress of water and non-compacting materials into the pavement system and to reduce the rate of pavement failure. Assessing and grading the condition of the pavement helps determine which pavement maintenance method is required. Sealing has been a necessary and important maintenance activity in asphalt pavements. Sealing cracks reduces the penetration of water and incompressible materials into the base and subbase layers, which leads to increased durability and life of the pavement. Currently, many new methods are used to stain damage and seal cracks.
It is essential to know which method and material is more economical in each situation. According to research, timely prevention can increase the useful life of asphalt by more than 10 years. Sealing is done with the help of an asphalt sealing machine.

Assessing and grading the condition of the pavement helps determine which pavement maintenance method is required. Sealing with appropriate polymer mastic, using special equipment and machinery, and by an experienced execution team, significantly increases the lifespan of the asphalt coating. Also, sealing cracks before resurfacing the asphalt significantly reduces the reflection of cracks into the new asphalt layer.
