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.
Some Important Definitions
![Page 11: Road way condition survey presentation final](https://reader031.vdocument.in/reader031/viewer/2022020714/55ad70251a28abc8128b4624/html5/thumbnails/11.jpg)
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.
Some Important Definitions

Pedestrian Refuge Island
Crosswalks may also include pedestrian refuge island
Potholes
Potholes usually develop in a surface that is either
cracked, raveled or both.
Some Important Definitions

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

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
