Cracking is one of the main concerns considered in the pavement design process. It is the primary mode of deterioration in asphalt cement pavements. Cracking occurs in a variety of forms: transverse, thermal, longitudinal, block, and alligator shapes. Cracks need to be treated promptly because they create openings for moisture & dust to penetrate into the pavement layers. Neglecting cracking usuÂally leads to accelerated deterioration of the pavement, resulting in significant problems such as potholes or base failures, which cause the serviceability of the pavement to decline. Also before new overlays the cracks shall be treated first.
