Roadway condition survey:A condition survey is the process of collecting data to determine the

structural integrity, distresses, skid resistance, and overall riding

quality of the pavement.

Provides the most valuable information for roadway performance analysis

Vital in order to forecast roadway performance, anticipate maintenance and

rehabilitation needs

Establish maintenance and rehabilitation priorities, and allocate funding

Purpose of roadway condition survey

To make a summary of the overall condition of the roadway

To make an historical record of roadway performance and maintenance practices

To justify warrant of traffic control devices

To study effectiveness of introduce schemes diagnosing given situation and finding appropriate situations

Alligator Cracking

It is a structural pavement failure that may be caused by

traffic overload, inadequate design thickness, base or sub-

grade failure, poor drainage, or a combination of these

factors.

Rutting

Rutting is a surface depression that typically occurs in the

wheel path(s) or at the edge of the pavement. Rutting

represents a structural failure.

Patching

Patching is only an indication of the amount of surface area

that has received some type of maintenance repair.

Some Important Definitions

10

Raveling

Raveling is identified by the loss of aggregate particles

from the pavement surface.

Random or Grid block cracks

Random block or grid block cracks divide the pavement

into rough rectangular or poly-angular pieces.

Transverse cracks

Transverse cracks are those considered to extend

greater than ¾ the width of the pavement generally

perpendicular to the centerline of the pavement.


11

Bleeding

Bleeding is a film of bituminous material on the

pavement surface that creates a shiny, reflective

surface. Bleeding is caused by excess asphalt

cement in the mix and/or low air void content.

Skid Resistance

Skid resistance, or surface friction, indicates the

ability of the pavement surface to provide

sufficient friction to avoid skid related safety

problems.


12

Pedestrian Refuge Island

Crosswalks may also include pedestrian refuge island

Potholes

Potholes usually develop in a surface that is either

cracked, raveled or both.


13

Zebra Crossing

Its distinguishing feature is alternating dark

and light stripes on the road surface, from

which it derives its name. A zebra crossing

typically gives extra rights of way to

pedestrian.

Ladder Crossing

Methods of Data Collection

15

Manual Survey Methods

Walking Survey :

Provides the most precise data about the condition

of the roadway.

surveys are completed by a rater who is trained to

rate distresses.

Windshield Survey :

survey is completed by driving along

the road or on the shoulder of the

road.

Allows a greater amount of coverage

in less time.

Walking + Windshield Survey :

Good method to achieve detailed pavement distress data

16

Automated Survey Methods

VIDEO CAMERA :

Observe service condition of roadway.

Recommendation

Geometric condition

• Pedestrian Refuge Island Should not too high

• The geometric layout of the roadway was not exactly

designed following road standards. There was a

continuous lack of symmetry throughout the length

of the road, especially at the intersections

41

42

Recommendation

Operating condition

Extra facilities for blind peoples and peoples who use wheelchair should be provided

The footpath should be cleared, clean and in good condition so that pedestrian can walk and use

footpath properly

Proper signs and markings on road is highly recommended

Retro reflective sign post panels should be provided

Roadside parking should be prevented and prohibited

U-turn should be restricted and minimized

43

Non Motorized Vehicles (NMV)

Shouldn’t Be Allowed In This

Road

Road Side Parking Should Be

Banned or Toll May Be

Collected To Discourage

Parking

Recommendation

Road Side Non-motor activities

Should Be Banned or

Prohibitted

44

Scattered And Haphazard

Pedestrian Crossing Should Be

Discouraged And Prohibited

Foot Over Bridges Should Be

Constructed At Important Points

For Pedestrian Crossings

Zebra Crossing Should be

Provided

Recommendation

Limitations

Limited and unskilled enumerators.

Time and Recourses was Limited
