A Pavement Management System (PMS) is used to make cost-effective decisions about design, construction, maintenance and rehabilitation of pavements.
Where – which pavement in the network
When – timing of Maintenance and Repair
What – what type of Maintenance and Repair to perform
2
PMS Should Answer the Following Questions
What is the current health of the pavement network?
Which pavement sections need work?
Which sections should be worked on first?
How much money do we need?
What impacts will funding changes have?

PASER Pavement Rating System
Previous surveys utilized PASERsystem
Based on a visual inspection of current rating
1-10 scale, 1-worst, 10-best No individual distress identification and
measurements

Distress Identification Manual
Benefits Consistent definitions
Standardized
Calibration
Degree of Sophistication PCI (Pavement Condition Index) – developed by US Army Corps of Engineers,
ASTM D5340 and D6433 for roads and airports – used in this study
LTPP (US, Network management)
PASER – Used by Michigan Counties
Manual Distress Surveys
Pre-survey activities Network definition
Sampling
10%-25% for network level
Higher for project level
Initial windshield survey
Detailed distress survey Record type, severity and extent
Distress Maps
Data Collection Method
Five groups of students evaluated all of the roads
PCI method of random sampling Sample size = 6 -9 slabs
Additional sampling of particularly deteriorated areas

Pavement Condition Index (PCI)
Present condition of the pavement based on the distresses observed on the surface
Deduct Curves apply weighing values for each distress.
Depend on: Distress Type
Severity
Amount of Density
ArcGIS Integration
Attractive way to display pavement management information
Combined system to track historical pavement data
Allows historical analysis of pavement repair effectiveness
Pavement deterioration monitoring

Pavement Rehabilitation Costs Pavement maintenance repair categories
Localized safety – Concrete patching
Localized preventive – Crack sealing
Global preventive – Crack sealing, Diamond grinding
Major Maintenance and Rehabilitation – Overlay, Reconstruction
22
Sample Unit Costs (Based on MDOT Unit Costs)
Localized safety and preventive type treatments $1.25/LF Crack/Joint Fill
$5.41/SF Slab Replacement
Major M&R treatments were not considered
Pavement Rehabilitation Cost Calculation PCI vs. Repair Cost per Square Feet was calculated based on a sample of pavement sections
Poor correlation
Can be improved by including all sections
