In CPCD, cracks are not intended and could cause performance problems. Examples include transverse and longitudinal cracks. From a pavement distress standpoint, transverse cracks are more serious than longitudinal ones, because wheel loads are applied to both sides of the crack in succession.
Crack filler has proven generally to perform from 1 to 2 years. Crack sealing is a long-term pavement preservation solution while crack filling is a band-aid. Pavement is always moving horizontally or vertically to some degree and therefore sealing is preferred over filling so that you can truly preserve the gigantic investment in our roads.Slot-stitching is the most economical repair method for restoring load transfer, preventing separations, and improving performance of longitudinal joints and wide cracks. In slot-stitching, slots with lengths no shorter than 25 in. are cut approximately perpendicular to the longitudinal joints or cracks using a slot cutting machine or walk ...
