Section 2: Definitions of Maintenance
Purpose of Definitions
Categories have been designed to assist the districts in the
performance of maintenance work and are intended to identify work
to be performed with maintenance funds. Maintenance funds should not
be used to perform construction work.
Definitions of Maintenance Work
Maintenance work is categorized into three areas:
- routine maintenance
- preventive maintenance
- major maintenance.All three maintenance categories may be performed with state forces or by contract; however, most preventive and major maintenance work should be contracted and funded with Strategy 144 maintenance funds or federal funds. Note that contracted work on Functional Class 6 and 7 roadways can only be completed using maintenance funds.The following definitions of maintenance activities should be used in determining the type of work activity when addressing planning and budgeting.
Travel Way
The table below defines travel way maintenance categories.
Routine Maintenance | Preventive Maintenance | Major Maintenance |
---|---|---|
Pavement-related work to include restoration of pavement service-ability including: recondition, rebuild, level up, and overlay. This would include, but not be limited to: pavement repair,
, bituminous levelups with light overlays to restore rideability (overlays not to exceed total average depth of 2”), additional base to restore rideability, and
. | Pavement-related work performed to prevent major deterioration of the pavement. Work would normally include, but not be limited to: milling or bituminous level-ups to restore rideability, light overlays (overlays not to exceed total average depth of 2”), seal coats, crack sealing and microsurfacing. Preparatory work such as milling, repairs or level-ups may also be performed. | Pavement-related work to strengthen the pavement structure for the current and projected future traffic usage. Work should include: restoration of pavement serviceability of roadway. This would include but not be limited to: recondition and stabilize base and subgrade, add base, level up, overlays and seal coats. Pavement widening can be considered major maintenance if done to correct a maintenance problem. |
Shoulder and Side Approaches
The following table defines maintenance categories for
and side approaches.
Routine Maintenance | Preventive Maintenance | Major Maintenance |
---|---|---|
All shoulder work to restore to its originally constructed condition including: recondition, rebuild, level-up and overlay. This work would also encompass installation and maintenance of public access drives, crossovers, turn lanes and mailbox turnouts. | All shoulder work to prevent major deterioration of the pavement including: milling or bituminous level-ups to restore cross section, light overlays (overlays not to exceed total average depth of 2”), seal coats, crack sealing and microsurfacing. Shoulder repair and widening not to exceed 26’ full roadway width. | All shoulder work to restore to its originally constructed condition and/or to strengthen the pavement structure for the current and projected future traffic usage, including but not limited to: recondition and/or stabilize base and subgrade, add base, level up, and seal coats. Adding shoulders, if done to correct a maintenance problem. |
Roadside
The table below defines roadside maintenance categories.
Routine Maintenance | Preventive Maintenance | Major Maintenance |

Repair or replacement of slopes and/or riprap to prevent damage
to structures or embankments. | Constructing new drainage channels
or modification of drainage structures to increase drainage capacity.
Performed only to correct a maintenance or safety problem or to
protect public or private property. |

The table below defines maintenance categories for structures.
Routine Maintenance | Preventive Maintenance | Major Maintenance |
---|---|---|
Repair of substructures, superstructures,
decks, joints, approach slabs and railing; spot painting; repair and
operation of movable bridges; installation of temporary bridges; repair
and installation of fender systems. | Steel structure cleaning and repainting

protection; joint cleaning and sealing or replacement. | Bridge rehabilitation, reconstruction,
or replacement. Replacement of structures only as a result of major
disaster when no other funds or programs are available. |
Traffic Operations
The following table describes maintenance categories for traffic operations.
Routine Maintenance | Preventive Maintenance | Major Maintenance |
---|---|---|
Installation, repair and replacement of signs, delineators, illumination, signals and related appurtenances; installation and replacement of striping, pavement graphics, raised pavement markings and rumble strips; maintenance of traffic control cabinets and the corresponding attachments (including but not limited to loop detectors, video cameras, changeable message signs, etc.). | Replacement of striping,

Emergency Operations
The table below defines maintenance categories for emergency

Routine Maintenance | Preventive Maintenance | Major Maintenance |
---|---|---|
Assistance to traffic during
accidents including traffic control, removal of debris and spilled cargo,
and snow and ice control. Assistance to traffic during other natural

imminent threat to life or property or to prevent disruption of
the orderly flow of traffic and commerce. Work off of the right
of way, such as assistance to cities, counties and individuals,
can be performed only when directed by the local Disaster District
Chairman (usually the local Department of Public Safety Captain),
Director of the Division of Emergency Management or the Governor. | None. | None. |
