Before any type of maintenance treatment for cracked pavement is undertaken the density and general condition of the cracks should be given consideration. If cracks are low to moderate in density, with a high degree of edge deterioration, then maintenance such as partial–depth patching or spot patching may be warranted. Chip seals, slurry seals, etc. may be more appropriate for pavements where cracks are abundant and exhibiting a low degree of edge deterioration. Pavements having low to moderate crack density with little to no edge deterioration can potentially be treated effectively through sealing or filling operations
As a rule, a large number of cracks or serious deteriorated cracks, indicating a pavement in an advanced state of disrepair. Crack sealing or filling in this circumstance is likely ineffective thus uneconomical for cracked pavements.It should take different measures to deal with different cracks.
