Asphalt crack sealing and commercial seal coating are both crucial aspects of maintaining asphalt surfaces, each serving distinct purposes. Crack sealing primarily aims to prevent water infiltration into the underlying layers of asphalt, which can lead to structural damage over time. This process involves filling or sealing cracks and joints in the pavement using specialized rubberized asphalt sealants, providing flexibility and durability to withstand various stresses.

On the other hand, commercial seal coating is focused on applying a protective layer over the entire surface of the asphalt. This coating acts as a shield against the elements, including UV rays, water, oil, and gasoline spills, as well as oxidation. It not only enhances the appearance of the pavement with a fresh, black finish but also prolongs its lifespan. Typically consisting of coal tar or asphalt emulsion mixed with additives, seal coating materials are designed to offer durability and resilience.

Together, these maintenance procedures work hand in hand to ensure the longevity and functionality of asphalt surfaces, making them essential components of pavement preservation efforts.
