WHAT IT IS PSI?
The Pavement Condition Index rates the condition
of the surface of a road network.

THE PCI MEASURES TWO CONDITIONS:
• The type, extent and severity of pavement surface distresses • The smoothness and ride comfort of the road

THE PCI IS A SUBJECTIVE METHOD OF EVALUATION BASED ON INSPECTION AND OBSERVATION
Method of PCI
By public works officials

WHAT IT PROVIDES ? : THE PCI TELLS PUBLIC WORKS OFFICIALS
-The current condition of the road network -The rate of deterioration of the road network

A PCI IS USED TO:
• Identify immediate maintenance and rehabilitation needs• Monitor pavement condition over time
![Page 8: Simple.. convenient.. inexpensive Prepared by Mohammed ALMannaa & Abdullah Asharef & Abdulrhman min Mahmoud.](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649ccf5503460f9499bab8/html5/thumbnails/8.jpg)
CONTINUE
• Develop a network preventive maintenance strategy• Develop road maintenance budgets
•Evaluate pavement materials and designs

A PCI NEEDS TO BE BASED ON:
Manageable road sections
A roads inventory
•A classification and rating system for road defects

Conducting a PCI
![Page 11: Simple.. convenient.. inexpensive Prepared by Mohammed ALMannaa & Abdullah Asharef & Abdulrhman min Mahmoud.](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649ccf5503460f9499bab8/html5/thumbnails/11.jpg)
THE DRIVE THROUGH:
A PCI is developed based on visual inspection and observation– sometimes
called a “windshield inspection.”
Ideally, two people should do the inspection together –one driving while the other takes notes – and both evaluating the pavement as they go.

CASE STUDY
![Page 15: Simple.. convenient.. inexpensive Prepared by Mohammed ALMannaa & Abdullah Asharef & Abdulrhman min Mahmoud.](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649ccf5503460f9499bab8/html5/thumbnails/15.jpg)
INTRODUCTION:
we choose three streets with different Performance and functional as a sample and build upon it using the PCI the quality of the district’s streets and
a precise results for these streets .
![Page 16: Simple.. convenient.. inexpensive Prepared by Mohammed ALMannaa & Abdullah Asharef & Abdulrhman min Mahmoud.](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649ccf5503460f9499bab8/html5/thumbnails/16.jpg)
OBJECTIVES:
Identify the distresses at field.Taking the PCI at field.
Calculate the resultEvaluation the street in Ar Rabia
![Page 17: Simple.. convenient.. inexpensive Prepared by Mohammed ALMannaa & Abdullah Asharef & Abdulrhman min Mahmoud.](https://reader036.fdocuments.net/reader036/viewer/2022062713/56649ccf5503460f9499bab8/html5/thumbnails/17.jpg)
We take a sample of three streets within the district abu moad alansary , alghtght and krimh alzbyryh
LOCATION:

PROCEDURE:
W depend on eye notice to the sample , so we walk on the street and write down the distresses that we see in a special form writing down the name of the distress & its number then we write its severity depending on an accurate measurement .also, we write its length if it is measured with width or its area if it is measured with area . then we calculate the index manually using the curves in the lecture note and deducts the points from 100. After that , we rate it using the pci rating figure &give its rating .we calculated the pci using an average of sections with all information above (severity , length , area,..) and a took pictures each of a distress.

RECOMMENDATION:
After taking the general assessment of the three ways, the result is good grade, so this sample represents the entire district of AR Rabia.
The final arbiter of the ways is good, so do not require re-asphalt the roads in this district.
