Region 1 Maintenance Guidelines for Pavement Restoration or Defective Work

This guideline applies anytime the asphalt saw cut does not fall at a lane line, striping is removed and not replaced in the same location or when defective paving has to be replaced.

Base Objective: Motorist cannot feel the repaired pavement. Prolong the working life of the asphalt pavement and reduce future maintenance costs.

Repair Guidelines:

1. Pavement condition new or like new (1‐3 years old): Complete a 2” grind and inlay with the same Level of ACP required in the contract (Level 3 minimum) for an area that covers the entire lane width of every lane affected by 100 foot long. The length to be centered on the defective/saw cut area if the defective area is small. If the area is larger than 100 feet then complete a 2” grind and inlay with the same Level of ACP required in the contract for an area that covers the entire lane width of every lane affected by the entire length of the defective/saw cut area.

2. Pavement condition anything less than new (3 years or older): Complete a 2” grind and inlay with the same Level of ACP required in the contract (Level 3 minimum) for an area that covers the entire lane width of every lane affected by 50 foot long. The length to be centered on the defective/saw cut area if the defective area is small. If the area is larger than 50 feet then complete a 2” grind and inlay with the same Level of ACP required in the contract for an area that covers the entire lane width of every lane affected by the entire length of the defective area.

3. When there are several smaller areas that are within a short distance of each other complete one continuous repair.

4. The District Manager or their designated representative will determine the limits of the repair based on these guidelines.
