A good time to do crack sealing is when an asphalt road or street is in fair to good condition. Along with proper drainage, crack sealing is probably the single most important maintenance activity. Most pavement distresses can be related to the intrusion of water into the pavement structure. If water is kept out of the pavement, the majority of distresses can be stopped or delayed.
Crack sealing is done with liquid asphalt, cutbacks and asphalt emulsions and is considered temporary work. In this article, we will focus on crack sealing.
