As part of a pavement maintenance system, crack sealing can significantly reduce pavement deterioration by preventing water penetration into the base and sub base layers
Crack sealing will not improve initial asphalt rideability, however, the benefits are realized in three to five years when it becomes quite obvious that the asphalt has not deteriorated any further.
At a time when manpower is shrinking, along with the funds to support road maintenance, crack sealing stands out as an economical maintenance technique. The overall success of pavement maintenance programs that include crack sealing, combined with the generally low cost, make crack sealing a highly desired technique by successful property managers and owners. Crack sealing provides the most cost-effective use of dollars over time compared to other pavement maintenance techniques.
