Because laying pavement the full width of the roadway in a single pass is not often possible, a single lane is poured, then another, creating seams between the lanes (also called longitudinal joints).

For cracks greater than one inch and pavement damage of depths up to two inches, GAP Mastic is a more durable and substantial repair solution than traditional crack sealants. Economical and versatile, GAP Mastic can be applied to wide cracks, cupping, depressions, fatigue cracking (alligatored areas), small voids and potholes, and open seams.
