1. Lane Closing

• Notify the public in advance about the upcoming maintenance work and the inconveniences it may cause.
• Clearly communicate the dates, times, and locations of lane closures to minimize disruption to commuters and ensure their safety.
• Use proper traffic control measures, including the use of cones, detour arrow signs, and other signals, to ensure a safe flow of traffic and guide drivers through the designated lanes.

2. Inspection and Marking

• Assess the condition of the highway surface to determine whether full-depth patching or partial depth patching is required.
• Opt for full-depth patching if there are longitudinal cracks that extend to a depth greater than 2 inches, or as specified in the specification.
• Go for partial depth if the crack is not that significant and has depth less than 2 inches or as specified in the specification.
• Use paint to mark the areas of the slab that need to be removed or patched.
