The appropriate type of Crack Sealing Machine maintenance for cracked pavement 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 Crack sealing or filling operations.
Crack density levels are described in general terms. This is because experienced personnel can make reasonable assessments of density. In general, a large number of cracks or severely deteriorated cracks indicate a pavement in an advanced state of decay. Crack sealing or filling in these circumstances is both uneconomical and technically unsound, as it does little to delay the need for more extensive corrective actions.
