Presented by:

The function of preserving, repairing, and restoring a highway and keeping it in condition for safe, convenient, and economical use is called Highway Maintenance.

Highway Maintenance is the routine work performed to keep a pavement, under normal conditions of traffic and normal forces of nature, as nearly as possible in its as constructed condition.

Highway Maintenance Definitions

It includes both physical maintenance activities such as sealing, patching, filling joints, and so forth and traffic service activities including painting pavement markings, removing snow, ice, and litter.

Rehabilitation includes restoring or betterment of roadway such as resurfacing.

What does highway maintenance includes?

FILLING THE JOINTS

RESURFACING

SNOW REMOVING

BITUMINOUS PATCHING

PAVMENT MARKING

Highway Maintenance Programs are designed to:

1) Offset the effects of weather2) Vandalism3) Vegetation growth4) Traffic wear and damage, as well as

deterioration due to the effects of aging5) Material failures6) Design and construction faults

Highway Maintenance Programs

All Pavements require maintenance. Stresses producing minor effects are

constantly working in all pavements. Stresses are:

◦ Change in temperature and moisture; ◦ Traffic; ◦ Small movements in underlying or adjacent earth.

Distresses are visible evidence of pavement wear (i.e. they are the end result of the wear process which begins when construction ends).

Water lines and other utilities are major area of pavement maintenance.

Importance of Highway Maintenance

To protect investments made in highways and to maintain the economic & safety of public road system highway maintenance becomes very necessary.
