introduction
  • A highway is any public road or other public way
    on land.
  • A main road, especially one connecting major
    towns or cities.
  • The first highway was constructed
  • on Long Island New York in the
  • United States in 1911.

4
Highway Pavements
  • Flexible Pavements- Bituminous pavement
  • Rigid Pavements- Cement concrete roads.

5
Highway failure
  • Main causes of pavement failures are-
  • Rutting due to high variation in temperature.
  • Uncontrolled heavy axle loads.
  • Inadequate Stability.
  • Loss of binding action.
  • Poor Design and Fabrication.

6
Highway failure Types
  • The four major types of pavement failure are
  • 1. Cracking (longitudinal cracks, etc.)
  • 2. Surface deformation ( Rutting, etc.)
  • 3. Disintegration (potholes, etc.)
  • 4. Surface defects (bleeding, etc.)

7
cracking
  • The most common types of cracking are
  • 1. Fatigue cracking
  • 2. Longitudinal cracking
  • 3. Transverse cracking
  • 4. Block cracking
  • 5. Slippage cracking
  • 6. Reflective cracking
  • 7. Edge cracking

Surface deformation
  • Pavement deformation is the result of weakness in
    one or more layers of the pavement.
  • The basic types of surface deformation are
  • 1. Rutting
  • 2. Corrugations
  • 3. Shoving
  • 4. Depressions
  • 5. Swell

11
disintegration
  • The progressive breaking up of the pavement into
    small, loose pieces is called disintegration.
  • If the disintegration is not repaired in its
    early stages, complete reconstruction of the
    pavement may be needed.
  • The two most common types of disintegration are
  • 1. Pot Holes
  • 2. Patches

13
Surface defects
  • Surface defects are related to problems in the
    surface layer.
  • The most common types of surface distress are
  • 1. Raveling
  • 2. Bleeding
  • 3. Polishing
  • 4. Delamination

15
Highway maintenance
  • The function of preserving, repairing, and
    restoring a highway.
  • It is essential for-
  • To  preserve the road in its originally
    constructed condition.
  • To provide user safety.
  • To provide efficient, convenient travel
  • along the route.

16
Materials used
  • Concrete
  • Bitumen
  • Asphalt
  • Gravel
  • Mineral Filler
  • Tar 

17
Highway maintenance includes
  • Physical maintenance
  • Activities such as sealing, patching, filling
    joints etc.
  • Traffic service activities
  • Including painting pavement markings, removing
    snow, ice, and litter.
  • Rehabilitation
  • Includes restoring or betterment of roadway such
    as resurfacing.

18
Types of maintenance
  • The various maintenance functions includes-
  • 1. Surface maintenance
  • 2. Roadside and drainage maintenance
  • 3. Shoulder and approaches maintenance
  • 4. Snow and ice control
  • 5. Bridges maintenance
  • 6. Traffic service

19
Surface maintenance
  • Periodic re-shaping of the road surface to ensure
    proper drainage and traffic passage.
  • Purpose of road surface maintenance
  • To provide safety to users.
  • Improve road performance.
  • lengthen maintenance cycles.
  • Reduce maintenance costs.

20
benefits
  • Benefits of surface maintenance
  • Creates a tightly packed road surface.
  • Reduces dust generation caused by the grinding
    action of large loose stone under traffic.
  • Minimizes loss of road material to erosion.
  • Gives a pleasant view.

21
Roadside and drainage maintenance
  • Clearing and cleaning of drains.
  • Reshape/re-grade ditch, line drain.
  • Clear manhole and underground
  • pipes.
  • Erosion repair.

22
shoulders
  • Obstructions washed onto the shoulders should be
    removed.
  • Vegetation control.
  • Reshape or re-grade shoulder
  • surface to the correct level.

23
Snow ice control
  • Ice reduces coefficient of friction between tires
    and surface.
  • Makes vehicle control almost impossible.
  • So snow from the roads
  • should be removed to
  • reduce the chances of
  • accidents.

24
Bridge Maintenance
  • Exposed steel work must be cleaned and repainted.
  • Cleaning and resealing of Deck joint.
  • Damage to guard rail, must be Repaired and
    strengthened.
  • Resurfacing of deck.
  • Scour around and under piers and abutments should
    be removed.

25
Traffic services
  • The installation of stop signs and other signs.
  • Repair of Traffic signals.
  • Pavement markings.

26
conclusion
  • Highway pavements plays an important role in
    convenience, warning direction.
  • There should be better management from time to
    time to keep the pavements in good condition.
  • Designing of pavements should be upgrade for
    better climate resistance.
