2015-9-16 Crack repair consists of crack sealing and crack filling. Usually, crack sealing re-fers to routing cracks and placing material on the routed channel. Crack filling, on the other hand, refers to the placement of mate-rial in/on an uncut crack. For the purposes of this manual, crack sealing will refer to both crack filling and sealing. Specifically, what is usually referred to as crack sealing will be referred to as crack sealing

Crack Seal is one of the most economical pavement maintenance tools for asphalt and concrete pavements. Crack Seal is a process in which a bituminous product is applied to open cracks and joints in a roadway surface. This process is the key to keeping water out of the pavement subbase which in turn will help provide long pavement service life.
