The appropriate type of maintenance for cracked pavements often depends on the density and general condition of the cracks. If cracks are abundant and do not exhibit a high degree of edge deterioration, they may best be treated through chip seals, slurry seals, or the like.
If cracks are low to moderate in density and have typically progressed to a point of high edge deterioration, then crack repair strategies, such as partial-depth patching or spot patching, may be warranted. If cracks are moderate in density and show moderate to no deterioration at the edges, then they may be treated effectively through sealing or filling operations. The guidelines should be summarized. This is because experienced personnel can make reasonable assessments of density.
