Best Practices for Crack Treatments for Asphalt Pavements
Crack sealing and crack filling are widely used treatments for maintenance of asphalt pavements. However, successful crack sealing and crack filling applications continue to be viewed as an art. When not properly applied, these pavement preservation treatments can result in early failures and costly corrective maintenance for highway agencies.

Longitudinal Cracking – Pavement Interactive
Top-down cracking. In pavements of substantial thickness for a given loading, cracking can initiate at the pavement surface (instead of at the bottom of the pavement layer). Cracks initiating at the pavement surface arise from tension induced by wheel loads combined with an aged, more brittle asphalt surface layer.
