Highway maintenance is the routine work needed to keep highways in safe and usable condition, and includes physical activities like sealing cracks and patching potholes as well as traffic services like removing snow and painting lines. Highway maintenance programs are designed to counteract the effects of weather, vandalism, plant growth, traffic wear, aging, material failures, and design flaws in order to protect investments in roads and maintain safety and economic benefits. Regular maintenance is required for all pavements as stresses from temperature, moisture, traffic, and earth movements constantly impact the road surface over time.

3.  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.

4.  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.

10.  Highway Maintenance Programs are
designed to:
1) Offset the effects of weather
2) Vandalism
3) Vegetation growth
4) Traffic wear and damage, as well as
deterioration due to the effects of aging
5) Material failures
6) Design and construction faults

11.  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.

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