PURPOSE AND TYPES OF MAINTENANCE AND REPAIR
the useful life of the pavement, maintain a smooth riding surface, and prevent water from entering
the underlying soil. Limited manpower and resources have increased the importance of M&R to
the life of a pavement. To keep a pavement in the best possible condition, it is important to use
an effective pavement management and inspection system. As pavements are repaired, it is
extremely important to analyze and repair the "true cause" of the pavement distress and not just
repair the distress. The intended function of pavements depends on proper and timely
maintenance and repair. To implement an effective pavement management and inspection
program, TM 5-826/AFR 93-5 and TM 5-623 should be used. These technical manuals describe
all ACC pavement distresses and severity levels.
2.2. Types of Maintenance and Repair. There are numerous types of M&R methods for ACC
pavements which include crack sealing (presented in UFC 3-270-02, "Asphalt Crack Repair"),
sealcoats, and overlays. This handbook presents the basic M&R procedures along with relevant
distresses. The handbook will not present overlays or new construction. M&R procedures
presented in this handbook include the following:
2.2.1. Full-depth and partial-depth patch. A full-depth patch is used to repair distresses such as
alligator cracking, corrugation, depression, oil spillage, rutting, swelling, edge cracking, and
bumps and sags, and replacing patches. A partial-depth patch is used to maintain/repair
distresses of low and medium severity, such as alligator cracking, corrugation, depression,
rutting, shoving, slippage cracking, swelling, and replacing patches.
