FY 2026-2030 HMIP Plans

:
G.S. 14​3B-350(f)(4a) ​requires that the NCDOT publish a schedule of State highway maintenance projects and their anticipated costs. This schedule is designat​ed the Highway Maintenance Improvement Program (HMIP) and is established in G.S. 136-44.3A. The published schedule shall include the anticipated funding sources for the improvement projects included in the HMIP.
​

Bridge​ Pro​je​cts​

BGOFF: Surface Transportation Block Grant Program (Off System)
BPR: Central Bridge Preservation
HFBD: Highway Fund Bridge Replacement Program (Division Funds)
HFBSW: Highway Fund Bridge Replacement Program (Statewide Funds)
NHPB: National Highway Performance Program (Bridge)
O: Local, Non-Federal or State Funds​

​Gene​ral Maintenance ​Projects​

​
RMIP Work Functions: The Highway Divisions create a five-year work plan for 32 work functions. Planned maintenance work activities/work functions are those that are performed on a recurring basis and can be planned to the route, system or asset level in advance of the work taking place. Planned Routine Maintenance activities are based on condition and level of service targets. Examples include shoulders and ditch maintenance, crossline pipe replacements, pavement striping, bridge joint repairs, mowing, ​and painting steel girders.

Budgeted Work Functions: In addition to the 32 planned work functions, Highway Divisions conduct unplanned routine maintenance work on over 140 budgeted work functions. Although the budgeted work functions are not planned to the asset level, the cost of these work functions are budgeted for within the Routine Maintenance Plan. These are activities that cannot be planned in advance and typically require an immediate response. Examples of these activities include pothole repair, removal of hazards and guardrail repair. 

Pavement Projects​​
​

Preservation: A treatment applied to a road in high fair to good condition that extends the pavement service life without substantially increasing the pavement structure (thickness). Typical pavement preservation treatments include bituminous surface treatments (chip seals), thin lift asphalt overlays, crack sealing, microsurfacing, and diamond grinding on concrete roadways.
 
Resurfacing: A hot mix asphalt overlay of an existing roadway. Resurfacing may consist of one or two lifts of asphalt surface course and may also consist of milling and replacing asphalt layers, microsurfacing, and other treatments. To minimize cost, a road should be resurfaced prior to the need for significant patching. The maximum thickness of resurfacing is two inches.
 
Rehabilitation: Significant work done to a road in poor to low fair condition, or to a r​oad requiring additional structure due to increased traffic loads. Rehabilitation frequently includes full-depth patching, leveling, deep milling, or multiple lift overlays.​
