Repairing a cracked sidewalk typically involves the use of specific materials and techniques. Here are some commonly used methods:

Spot Repair: Spot repair involves fixing individual cracks or small sections of the sidewalk. This method is suitable when the cracks do not pose a tripping hazard or other forms of deterioration .

Complete Replacement: At some point, it may be necessary to completely replace the sidewalk or specific sections (panels). This process involves the removal and replacement of the damaged sidewalk sections. It is often employed when spot repairs are no longer sufficient .

Throw-and-Roll Method: The throw-and-roll method is one of the techniques used for repairing cracks in pavement. It involves cleaning the debris from the crack and then applying a patching material by throwing it into the crack and rolling it with a heavy vehicle or roller .

Semi-Permanent Repair: Semi-permanent repair is another method used for fixing pavement cracks. It involves cleaning the crack, applying a tack coat, and then filling the crack with a hot mix asphalt material. This method provides a longer-lasting repair compared to temporary solutions.

Spray Injection: Spray injection is a technique used for repairing pavement cracks. It involves using specialized equipment to clean the crack, apply a tack coat, and then fill the crack with a polymer-modified asphalt emulsion. This method provides a more durable and long-lasting repair .
