Sunflower Village Pavement Management

By: Dr. Nishantha Bandara, Remington Koch & Susan Henson

1

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

Pavement Management in Action

3

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?

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

Pavement Distress Surveys

Characterization of distresses by

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

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

ArcGIS Integration

Attractive way to display pavement management information

Combined system to track historical pavement data

Allows historical analysis of pavement repair effectiveness

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

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

Sample Repair Recommendation

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
