NCLUDES Stitching Concrete Pavement Cracks and Joints

There are two stitching methods used to repair and strengthen cracks or joints in pavement. The first, and most common, is cross-stitch-ing. Cross-stitching uses deformed tiebars epoxied or grouted into holes drilled at an angle through a crack. The second, slot-stitching, uses deformed tiebars grouted into slots cut across a joint or crack.

Asphalt Services: TARC Construction Inc.

Unless the cracks are repaired, the entire lot will have to be completely removed. Solution: Grind, or slot cut the perimeter of the alligatored areas. Compact sub-base to 90-95 percent compaction. Tack vertical edges and install hot asphalt in equal lifts and roll for proper compaction.

Stitching Concrete Pavement Cracks and Joints. There are two stitching methods used to repair and strengthen cracks or joints in pavement. The first, and most common, is cross- stitching. Cross-stitching uses deformed tie bars epoxied or grouted into holes drilled at an angle through a crack. The second, slot-stitching, uses deformed tie bars grouted into slots cut across a joint or crack.

Stitching – Pavement Interactive

In slot-stitching, slots with lengths no smaller than 25 inches are cut approximately perpendicular to the longitudinal joints or cracks using a slot cutting machine or walk-behind saw. Slots are prepared by removing the and cleaning the slot. Deformed bars are placed and backfill material is applied, finished, and cured.

Construction and Materials Tips

In slot stitching, rectangular cavities, or “slots,” are saw-cut perpendicular to and centered over the joint or crack at the specified depth and spacing in order to provide enough clearance for the tie bars and their underlying support devices to be placed at mid-depth of the slab.

Pavement Failure Warning Signs - Tarc Construction Inc.

This is called “alligator cracking,” also known as “fatigue cracking.” Unless the cracks are repaired, the entire lot will have to be completely removed. Solution: Grind or slot cut the perimeter of the alligator-cracked areas. Compact sub-base to 90-95 percent compaction.
