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

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

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

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.
