The purpose of sealing cracks in asphalt pavements is to protect the pavement structure from premature failure. The use of proper crack preparation and sealing techniques can extend the effective life of the sealant, thereby increasing the life of the pavement and reducing maintenance costs. Unsealed cracks allow water intrusion and debris retention in the crack opening. Water intrusion in the cracks penetrates into the base and subbase materials, creating the potential for a loss of strength in these materials. The weakened pavement structure can result in load-related failures such as alligator cracking. The debris retention can cause the pavement to “push up” at the edges of the crack when the pavement expands due to thermal changes. This decreases the rideability of the pavement surface. These failures and deficiencies increase the lifecycle cost of the pavements by requiring increased maintenance.
